The sniffer then confirms that five packets were seen by that network interface. Type the packet capture command, such as: diagnose sniffer packet port1 'tcp port 541' 3 100 . Similar to mathematics, there is an order of operation. In my lab, I have a lot of ICMP traffic so I will filter it further and only choose to capture packets destined to 3.210.115.14 (fortinet.com), diag sniffer packet any "host 3.210.115.14 and icmp" 4 l 0. Enter one or more ports to capture on the selected interface. The number of packets the sniffer reads before stopping. So the first thing to note is that since FortiGate is such and amazing platform (I know I am biased) and has the advent of ASICs, by default, we do not see the packets that are getting offloaded to the SOC and NOC ASICs. Surround the filter string in quotes. Technical Tip: Packet capture (sniffer) This article describes the built-in sniffer tool that can be used to find out the traffic traversing through different interfaces. The level of verbosity as one of:1 - print header of packets2 - print header and data from IP of packets3 - print header and data from Ethernet of packets4 - print header of packets with interface name. Johannes Weber says: 2016 . Because port 22 is used (highlighted above in bold), which is the standard port number for SSH, the packets might be from an SSH session. The filters below find these various packets because tcp[13] looks at offset 13 in the TCP header, the number represents the location within the byte, and the !=0 means that the flag in question is set to 1, i.e. If you do not specify a number, the command will continue to capture packets until you press Ctrl+C. Resources. Usefull Fortigate CLI commands. To display only the traffic between two hosts, specify the IP addresses of both hosts. Use this feature to capture non-IP based packets. FortiAnalyzer units have a built-in sniffer. A specific number of packets to capture is not specified. Description This article describes one of the troubleshooting options available in FortiGate CLI to check the traffic flow, by capturing packets . The capture uses a high level of verbosity (indicated by3). This blog post is a list of common troubleshooting commands I am using on the FortiGate CLI. You can select the filter and start capturing packets. diagnose: diagnose sniffer packet Use this command to perform a packet trace on one or more network interfaces. You must select one interface. When the filter is running, the number of captured packets increases until it reaches the Max Packet Count or you stop it. The name of the interface to sniff, such as port1 or internal. When you add a packet capture filter, enter the following information and click OK. Network Security. The following example captures packets traffic on TCP port 80 (typically HTTP) between two hosts, 192.168.0.1 and 192.168.0.2. Because port 22 is used (highlighted above in bold), which is the standard port number for SSH, the packets might be from an SSH session. dia sniffer packet any "tcp[13] & 4 != 0", Here is an example of capturing packets that match the SYN (SYNchronization) For example, you could use PuTTY or Microsoft HyperTerminal to save the sniffer output. What to look for in the information the sniffer reads. If you are familiar with the TCP protocol, you might notice that the packets are from the middle of a TCP connection. To enter a range, use a dash without spaces, for example 88-90. Because the filter does not specify either host as the source or destination in the IP header (src or dst), the sniffer captures both forward and reply traffic. A large amount of data may scroll by and you will not be able to see it without saving it first. Now we will cover the sniffer command. The following example captures three packets of traffic from any port number or protocol and between any source and destination (a filter of. diagnose sniffer packet port1 'tcp port 541' 3 100. FortiAnalyzer # diag sniffer port1 'tcp port 443' 3, 10.651905 192.168.0.1.50242 -> 192.168.0.2.443: syn 761714898. To display only forward or reply packets, indicate which host is the source, and which is the destination. To display only forward or only reply packets, indicate which host is the source, and which is the destination. | Terms of Service | Privacy Policy, diag sniffer packet port1 'host 192.168.0.2 or host 192.168.0.1 and tcp port 80' 1, Using the FortiOS built-in packet sniffer, otherwise: relative to the start of sniffing, ss.ms, network protocol analyzer software such as. (A.K.A. This displays the next three packets on the port1 interface using no filtering, and verbose level 1. The sniffer then confirms that five packets were seen by that network interface. To minimize the performance impact on your FortiMail unit, use packet capture only during periods of minimal traffic, with a serial console CLI connection rather than a Telnet or SSH CLI connection, and be sure to stop the command when you are finished. 2) Save this fgt2eth.exe on a specific folder. execute command like tcpdump # diagnose sniffer packet port15 Interface Port15 # diagnose sniffer packet any 'host xx.xx.xx.xx' # diagnose sniffer packet port15 'host xx.xx.xx.xx' # diagnose sniffer packet any 'host xx.xx.xx.xx or host yy.yy.yy.yy' # diagnose sniffer packet any 'udp port 53 or tcp port 53' # diagnose sniffer packet any .

Packet capture is displayed on the CLI, which you may be able to save to a file for later analysis, depending on your CLI client. Use this command to perform a packet trace on one or more network interfaces. FortiADC appliances have a built-in sniffer. The capture uses a low level of verbosity (indicated by 1). Select the interface to sniff from the drop-down menu. To minimize the performance impact on your, type of service/differentiated services code point (. And always remember When in doubt, sniff it out, Have you ever installed a Windows server to do Full Story, Why would you need to export the private key Full Story, I had a customer that installed a wildcard certificate Full Story, 2021 InfoSec Monkey | Design by Fitser, Quick-Tip : Debugging IPsec VPN on FortiGate Firewalls. A dialog appears where you can configure PuTTY to save output to a plain text file. Packet capture, also known as sniffing or packet analysis, records some or all of the packets seen by a network interface (that is, the network interface is used in promiscuous mode). If you omit this and the following parameters for the command, the command captures all packets on all network interfaces. Packet capture output appears on your CLI display until you stop it by pressing Ctrl+C, or until it reaches the number of packets that you have specified to capture. Enter one or more protocols. SSH. For troubleshooting purposes, Fortinet Technical Support may request the most verbose level (3). This article describes how the output of the 'diag sniff packet' command can be imported into Wireshark. A mnemonic sometimes used to remember the TCP Flags is, Unskilled Attackers Pester Real Security Folks, Here is an example of capturing packets that match the RST (Reset) To enter a range, use a dash without spaces. For additional information on the packet sniffer utility, see the Fortinet Knowledge Base article, diagnose sniffer packet [{any| } [{none| ''} [{1 | 2 | 3} []]]], Type the name of a network interface whose packets you want to capture, such as. diagnose sniffer packet internal " port 6060 and (ether[0x90]=23 or ether[0x90]=24 or ether[0x90]=25 or ether[0x90]=26) " Note that 0x17 = 23. For example, to display UDP port 1812 traffic between 1.example.com and either 2.example.com or 3.example.com, you would enter: 'udp and port 1812 and src host 1.example.com and dst \(2.example.com or 2.example.com \)'. To download fgt2eth.pl, see the Fortinet Knowledge Base article Using the FortiOS built-in packet sniffer. FortiADC # diagnose sniffer packet port1 'host 192.168..2 or host 192.168..1 and tcp port 80' 1. The sniffer then confirms that five packets were seen by that network interface. Packet capture can be very resource intensive. If you don't put a number here, the sniffer will run until you stop it with . One method is to use a terminal program like puTTY to connect to the FortiGate CLI. If you are familiar with the TCP protocol, you may notice that the packets are from the middle of a TCP connection. As a result, output shown below is truncated after only one packet. Type either none to capture all packets, or type a filter that specifies which protocols and port numbers that you do or do not want to capture, such as 'tcp port 25'. diagnose sniffer packet [{any| } [{none| ''} [{1 | 2 | 3} []]]]. If you do not delete them, they could interfere with the script in the next step. Although I am using ICMPas the protocol, you CAN choose to use TCP or UDP as well. Because the filter does not specify either host as the source or destination in the IP header (src or dst), the sniffer captures both forward and reply traffic. Use PuTTY to connect to the Fortinet appliance using either a local serial console, SSH, or Telnet connection. Head_Office_620b # diagnose sniffer packet port1 none 1 3, 0.545306 172.20.120.17.52989 -> 172.20.120.141.443: psh 3177924955 ack 1854307757, 0.545963 172.20.120.141.443 -> 172.20.120.17.52989: psh 1854307757 ack 3177925808, 0.562409 172.20.120.17.52988 -> 172.20.120.141.443: psh 4225311614 ack 3314279933. The capture uses a low level of verbosity (indicated by 1). Packet capture on FortiADC appliances is similar to that of FortiGate appliances. You can also see the filter status and the number of packets captured. To use packet capture, the FortiGate must have a disk. A specific number of packets to capture is not specified. In the above example, I am looking for ONLY ICMP traffic. For this we can use the ! but do not press Enter yet. To minimize the performance impact on your FortiAnalyzer unit, use packet capture only during periods of minimal traffic, with a serial console CLI connection rather than a Telnet or SSH CLI connection, and be sure to stop the command when you are finished. FortiGate / FortiOS; FortiGate 5000; FortiGate 6000; FortiGate 7000; FortiProxy; NOC & SOC Management The second example shows 2which corresponds to Swhich is the SYN flag. none indicates no filtering, and all packets are displayed as the other arguments indicate.The filter must be inside single quotes (). Usefull Fortigate CLI commands. but do not press Enter yet. Packet capture output is printed to your CLI display until you stop it by pressing CTRL+C, or until it reaches the number of packets that you have specified to capture. NOTE: Anything that matches this filter will be captures. diag sniffer packet any "src 10.1.105.3 and icmp" 4 l 0. Use this command to perform a packet trace on one or more network interfaces. diagnose sniffer packet - this is the base command interface - You can either choose the interface specifically or use the keyword any options - here you can filter the capture by IP, protocol . We then see if egress port1which is my AT&T Gigapower circuit. Select this option if you are troubleshooting IPv6 networking, or if your network uses IPv6. The following command is used to trace packets. If you omit this and the following parameters for the command, the command captures all packets on all network interfaces. Once they get the information, I usually do not hear from them again and things just start working. This is much easier to troubleshoot because we do not need to collect unnecessary packets. '[[src|dst] host { | }] [and|or] [[src|dst] host { | }] [and|or] [[arp|ip|gre|esp|udp|tcp] port ] [and|or] [[arp|ip|gre|esp|udp|tcp] port ]'. Note: It will ONLY show the outbound traffic since you specified srcand once it gets source NATd, it will no longer match the filter. You must use a third party application, such as Wireshark, to read *,pcap files. # diagnose sniffer packet any 'net 1.1.1.0/24 and net 2.2.2.0/24' 4 0 l. Once the packet sniffing count is reached, you can end the session and analyze the output in the file. '[[src|dst] host { | }] [and|or] [[src|dst] host { | }] [and|or] [[arp|ip|gre|esp|udp|tcp] port ] [and|or] [[arp|ip|gre|esp|udp|tcp] port ]'. 1) Download the fgt2eth.exe (For Windows Users) . FortiADC appliances have a built-in sniffer. To display only forward or reply packets, indicate which host is the source, and which is the destination. Commands that you would type are highlighted in bold; responses from the FortiADC appliance are not bolded. When you are SSHd to the Fortigate which I usually am when running these commands, you CAN be overwhelmed by the very connection you are using. In the examples above, we can see that 4is in the Rcolumn which corresponds to the RST or Reset Flag. Hover over the symbol to reveal explanatory text. Type the packet capture command, such as: In the upper left corner of the window, click the PuTTY icon to open its drop-down menu, then select. On your management computer, start PuTTY. GitHub Gist: instantly share code, notes, and snippets. For example, to display UDP port 1812 traffic between 1.example.com and either 2.example.com or 3.example.com, you would enter: 'udp and port 1812 and src host 1.example.com and dst \(2.example.com or 2.example.com \)'. Type one of the following numbers indicating the depth of packet headers and payloads to capture: For troubleshooting purposes, Fortinet Technical Support may request the most verbose level (3). Select this option to specify filter fields. Copyright 2018 Fortinet, Inc. All Rights Reserved. Separate multiple hosts with commas. diagnose sniffer packet . The protocols in the list are all IP based except for ICMP (ping). Open the packet capture file using a plain text editor such as Notepad++. Separate multiple ports with commas. As a result, the packet capture continues until the administrator presses Ctrl+C. In the output below, port 443 indicates these are HTTPS packets and that 172.20.120.17 is both sending and receiving traffic. Usually they are quick easy commands to make your day brighter and help you finish up quicker so you can enjoy family, friends, and libations. Type either none to capture all packets, or type a filter that specifies which protocols and port numbers that you do or do not want to capture, such as 'tcp port 25'. Enter one or more VLANs (if any). Packet Capture. Solution. I have been in the networking and security industry for about 29 years as of this writing and I have always lived my a strict motto; and anyone that has worked with me in the past knows this well. Commands that you would type are highlighted in bold; responses from the Fortinet unit are not in bold. You can convert the plain text file to a format (.pcap) recognizable by Wireshark using the fgt2eth.pl Perl script. 3 All of the output from 2, plus the the link layer (Ethernet) header. dia sniffer packet any "tcp[13] = 18". Finally on the third we see 18which is 16+2giving us the SYN/ACK. <count> <----- The number of packets to capture. Surround the filter string in quotes ('). When troubleshooting networks . FGT# diagnose sniffer packet any "host <PC1> or host <PC2> or arp" 4 . This tool provides you with extensive analytics and the full contents of the packets that were captured. Lets look at an example. As you can see the options are enableor disable, The other option is to go through the GUI and choose the Policy you want to disable offload on. The following CLI command for a sniffer includes the ARP protocol in the filter which may be useful to troubleshoot a failure in the ARP resolution. So as an example, If I am pinging 3.210.115.14from 10.1.105.3but then from 10.1.105.3I start to ping 4.2.2.2that will also be picked up since I am capturing any ICMP from or to any of those two hosts. To use fgt2eth.pl, open a command prompt, then enter a command such as the following: fgt2eth.pl -in packet_capture.txt -out packet_capture.pcap. For additional information on packet capture, see the Fortinet Knowledge Base article Using the FortiOS built-in packet sniffer. . These lines are a PuTTY timestamp and a command prompt, which are not part of the packet capture. dia sniff packet any "(src 10.1.105.3 or src 10.1.105.1) and icmp" 4 l 0, This will give you any ICMP packet that is sourced from 10.1.105.3or sourced from 10.1.105.1, So this is probably one of my most used filters. Packet capture, also known as sniffing, records some or all of the packets seen by a network interface. The capture uses a low level of verbosity (indicated by 1). Methods may vary. Network Security. With verbosity 4 and above, the sniffer trace displays the interface names where traffic enters or leaves the FortiGate unit. This is helpful when you want to see traffic from a particular set of hosts. You cannot download the output file while the filter is running. To display only the traffic between two hosts, specify the IP addresses of both hosts. For example, 172.16.1.5-172.16.1.15, or enter a subnet. If you do not specify a number, the command will continue to capture packets until you press Ctrl+C. You can also see pre and post NAT (Network Address Translation). The following example captures packets traffic on TCP port 80 (typically HTTP) between two hosts, 192.168.0.1 and 192.168.0.2. . Separate multiple protocols with commas. The capture uses a low level of verbosity (indicated by 1). I will be 100% honest with you. If you are familiar with the TCP protocol, you might notice that the packets are from the middle of a TCP connection. If you select a filter, you have the option to start and stop packet capture in the edit window, or download the captured packets. So you see the packet coming in with a 10.1.105.3 IP address which is what DHCP gave my MacBook Pro. 3) Then access to the unit using putty or any other ssh application. Then when it egresses through port1we can see that it has NATd (source-NAT) the IP to a 23address. As a result, the packet capture continues until the administrator presses CTRL + C. The sniffer then confirms that five packets were seen by that network interface. A specific number of packets to capture is not specified. '[[src|dst] host { | }] [and|or] [[src|dst] host { | }] [and|or] [[arp|ip|gre|esp|udp|tcp] port ] [and|or] [[arp|ip|gre|esp|udp|tcp] port ]'. Home; Product Pillars. Below is a sample output. To do a sniff, follow the syntax below: # diagnose sniffer packet <interface> <'filter'> <level> <count> <tsformat>. Type one of the following integers indicating the depth of packet headers and payloads to capture: For troubleshooting purposes, Fortinet Technical Support may request the most verbose level (. Enter the IP address of one or more hosts. Type the name of a network interface whose packets you want to capture, such as port1, or type any to capture packets on all network interfaces. To view packet capture output using PuTTY and Wireshark: On your management computer, start PuTTY. Use this command to perform a packet trace on one or more network interfaces. We described the limitations on the previous section. To start, stop, or resume packet capture, use the symbols on the screen. To display only the traffic between two hosts, specify the IP addresses of both hosts. Instead of reading packet capture output directly in your CLI display, you usually should save the output to a plain text file using your CLI client. Now in this output, you will see the that we are seeing the inand the outsince the destination IP stays the same preand postNAT. When you are running a capture and are not seeing what you are expecting to see, you may need to disable the offloading on that particular policy. To minimize the performance impact on your FortiManager unit, use packet capture only during periods of minimal traffic, with a serial console CLI connection rather than a Telnet or SSH CLI connection, and be sure to stop the command when you are finished.# diag sniffer packet port1 'host 192.168..2 or host 192.168..1 and tcp port 80' 1 The following sniffer CLI command includes the ARP protocol in the filter which may be useful to troubleshoot a failure in the ARP resolution (for instance PC2 may be down and not responding to the FortiGate ARP requests). As a result, the packet capture continues until the administrator presses Ctrl+C. In this example the test unit is continuously pinging 8.8.8.8. dia sniffer packet any "tcp[13] & 2 != 0", Here is an example of capturing packets that match the SYN/ACK (SYNchronization / ACKnowledgement) Now lets get laser focussed. FortiADC-VM # diagnose sniffer packet port1 none 1 3, 0.000000 172.30.144.20.53800 -> 172.30.144.100.22: ack 202368347. If you do not specify a number, the command will continue to capture packets until you press Control +C. The following example captures the first three packets worth of traffic, of any port number or protocol and between any source and destination (a filter of none), that passes through the network interface named port1. Press Enter to send the CLI command to the FortiMail unit, beginning packet capture. Packet capture on FortiAnalyzer units is similar to that of FortiGate units. Examples of non-IP packets include IPsec, IGMP, ARP, and ICMP. # diagnose sniffer packet any 'net 2001:db8::/32' 6 1000 l. Reply. FGT# diagnose sniffer packet any "host or host " 4, FGT# diagnose sniffer packet any "(host or host ) and icmp" 4. The sniffer then confirms that five packets were seen by that network interface. diag sniffer packet any "dst 8.8.8.8 and icmp" 4 l 0. The following example captures packets traffic on TCP port 80 (typically HTTP) between two hosts, 192.168.0.1 and 192.168.0.2. You can download the *.pcap file when the packet capture is complete. Before you start sniffing packets, you should prepare to capture the output to a file. FortiADC # diagnose sniffer packet port1 'host 192.168..2 or host 192.168..1 and tcp port 80' 1. By recording packets, you can trace connection states to the exact point at which they fail, which may help you to diagnose some types of problems that are otherwise difficult to detect. Example of network as a filter: First filter: Sniff from two networks. The fgt2eth.pl script is provided as-is, without any implied warranty or technical support, and requires that you first install a Perl module compatible with your operating system. When you troubleshoot networks and routing in particular, it helps to look inside the headers of packets to determine if they are traveling the route that you expect them to take. FortiAnalyzer# diag sniffer packet port1 'host 192.168.0.2 or host 192.168.0.1 and tcp port 80' 1, 192.168.0.2.3625 -> 192.168.0.1.80: syn 2057246590, 192.168.0.1.80 -> 192.168.0.2.3625: syn 3291168205 ack 2057246591, 192.168.0.2.3625 -> 192.168.0.1.80: ack 3291168206, 192.168.0.2.3625 -> 192.168.0.1.80: psh 2057246591 ack 3291168206, 192.168.0.1.80 -> 192.168.0.2.3625: ack 2057247265. Sniffer Command. Use PuTTY to connect to the Fortinet appliance using either a local serial console, SSH, or Telnet connection. Packets can arrive more rapidly than you may be able to read them in the buffer of your CLI display, and many protocols transfer data using encodings other than US-ASCII. The capture uses a low level of verbosity (indicated by, FortiADC# diagnose sniffer packet port1 'host 192.168.0.2 or host 192.168.0.1 and tcp port 80' 1. GitHub Gist: instantly share code, notes, and snippets. Most of the time I spend Troubleshooting it is usually collecting packet captures, debug output, etc to send to the people blaming me for the problem. Type the number of packets to capture before stopping. Does not display all fields of the IP header; it omits: 2 All of the output from 1, plus the packet payload in both hexadecimal and ASCII. Verbose output can be very long. Packet capture can be very resource intensive. FortiADC# diagnose sniffer packet port1 'host 192.168.0.2 or host 192.168.0.1 and tcp port 80' 1. FGT# diagnose sniffer packet any "host or host or arp" 4. For example, to display UDP port 1812 traffic between 1.example.com and either 2.example.com or 3.example.com, you would enter: 'udp and port 1812 and src host 1.example.com and dst \(2.example.com or 2.example.com \)'. The general form of the internal FortiOS packet sniffer command is: diagnose sniffer packet <interface_name> <'filter'> <verbose> <count> <tsformat>. Now we are going to add some options so we can see how those command look. You cannot change the interface without deleting the filter and creating a new one, unlike the other fields. To minimize the performance impact on your FortiADC appliance, use packet capture only during periods of minimal traffic, with a local console CLI connection rather than a Telnet or SSH CLI connection, and be sure to stop the command when you are finished. Below is a sample output. Packet capture can be very resource intensive. Packet capture, also known as sniffing or packet analysis, records some or all of the packets seen by a network interface (that is, the network interface is used in promiscuous mode). Another thing you can do is combine multiple hostcommands with anand, diag sniffer packet any "host 3.210.115.14 and host 10.1.105.3 and icmp" 4 l 0. See the documentation for your CLI client. Otherwise, leave it disabled. You can enable the capture-packet in the firewall policy. Type the number of packets to capture before stopping. It is not complete nor very detailled, but provides the basic commands for troubleshooting network related issues that are not resolvable via the GUI. For example, 1-6, 17, 21-25. Part of successfully troubleshooting is learning packet capture. Open the converted file in your network protocol analyzer application. Saving the output provides several advantages. 192.168.0.2.3625 -> 192.168.0.1.80: syn 2057246590, 192.168.0.1.80 -> 192.168.0.2.3625: syn 3291168205 ack 2057246591, 192.168.0.2.3625 -> 192.168.0.1.80: ack 3291168206, 192.168.0.2.3625 -> 192.168.0.1.80: psh 2057246591 ack 3291168206, 192.168.0.1.80 -> 192.168.0.2.3625: ack 2057247265, config global-dns-server remote-dns-server, config global-dns-server response-rate-limit, config global-dns-server trust-anchor-key, config global-load-balance virtual-server-pool, config load-balance real-server-ssl-profile, config load-balance reputation-black-list, config security dos dos-protection-profile, config security dos http-connection-flood-protection, config security dos http-request-flood-protection, config security dos ip-fragmentation-protection, config security dos tcp-access-flood-protection, config security dos tcp-slowdata-attack-protection, config security dos tcp-synflood-protection, config security waf heuristic-sql-xss-injection-detection, config security waf http-protocol-constraint, config security waf input-validation-policy, config security waf parameter-validation-rule, config security waf json-validation-detection, config security waf xml-validation-detection, config security waf openapi-validation-detection, config system certificate certificate_verify, config system certificate intermediate_ca, config system certificate intermediate_ca_group, config system certificate local_cert_group, execute SSL client-side session statistics, Using the FortiOS built-in packet sniffer, Packet capture can be very resource intensive. Here are some examples. Packet capture output appears on your CLI display until you stop it by pressing Ctrl+C, or until it reaches the number of packets that you have specified to capture. Use PuTTY to connect to the Fortinet appliance using either a local serial console, SSH, or Telnet connection. Packet sniffing is also known as network tap, packet capture, or logic analyzing. If 0 or no value is defined, unlimited packets will be capture until ctrl+c is . The following example captures three packets of traffic from any port number or protocol and between any source and destination (a filter of none), which passes through the network interface named port1. Delete the first and last lines, which look like this: Convert the plain text file to a format recognizable by your network protocol analyzer application. The following example captures all TCP port 443 (typically HTTPS) traffic occurring through port1, regardless of its source or destination IP address. Type one of the following integers indicating the depth of packet headers and payloads to capture: 1 Display the packet capture timestamp, plus basic fields of the IP header: the source IP address, the destination IP address, protocol name, and destination port number. The following commands will report packets on any interface that are traveling between a computer with the host name of PC1 and a computer with the host name of PC2. 192.168.0.2.3625 -> 192.168.0.1.80: syn 2057246590, 192.168.0.1.80 -> 192.168.0.2.3625: syn 3291168205 ack 2057246591, 192.168.0.2.3625 -> 192.168.0.1.80: ack 3291168206, 192.168.0.2.3625 -> 192.168.0.1.80: psh 2057246591 ack 3291168206, 192.168.0.1.80 -> 192.168.0.2.3625: ack 2057247265, Using the FortiOS built-in packet sniffer.
