Regards, The tunnel is created between the public IPs, not the private VTI ones. Thanks for your reply. Step 6. But my articles are made from the stuff Im working on. Wow man, after a hard night you saved me from doing something bad Thanks a lot, perfect! Step 7. Thank goodness for that. With VTI, deployments become much easier to manage. On the IKEV1 IPsec Proposal window, add your new IPsec policy to the Selected Transform Sets section and click OK . SK_ai: I am, If you look at the ISR post elsewhere on the site, I think it also uses a 169.254 address.169.254.225.2 is not assigned to anything, nor does it have to be. Step 1: Configuring a VPN policy on Site A SonicWall. 2022 Cisco and/or its affiliates. Delivery time is estimated using our proprietary method which is based on the buyer's proximity to the item location, the shipping service selected, the seller's shipping history, and other factors. The information that conflicts IKEv2 attribute from Microsoft is visible here. ), For IKEv2 route-based VPN that uses crypto map on ASA with policy-based traffic selectors: ASA code version 8.2 or later configured with a crypto map. Add an IPSec profile that specifies: Note: Microsoft has published information that conflicts with regard tothe particular phase 2 IPSeclifetime and PFS attributes used by Azure. Create an IKEv2 policy that defines the algorithms/methods to be used for hashing, authentication, DH group, PRF, lifetime, and encryption. If you are a networking type its part of the virtual network, but is more specific than the subnet you already created.. Verify the phase 2 IPSec security association has built with show crypto ipsec sa peer [peer-ip] . It should be limited to necessary traffic only! selectors set security-association lifetime seconds 3600, crypto ikev2 policy 2 With a route based VPN, all traffic sent out or received via the tunnel interface will be VPN traffic (and ttherefor encrypted). outbound $129.99. Important. set remote-gw 1.1.1.1 Step 1. Give the tunnel a name > Site-to-Site IPSec > Select your Local Network Gateway (ASA) > Create a pre-shared-key (you will need this for the ASA config!) spi: 9f02578f Step 15. tunnel-group 2.2.2.2 general-attributes document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Privacy Policy | Copyright PeteNetLive 2022, Microsoft Azure Route Based VPN to Cisco ASA, crypto ipsec ikev2 ipsec-proposal AZURE-PROPOSAL, protocol esp integrity sha-384 sha-256 sha-1, ip address 169.254.225.1 255.255.255.252, tunnel protection ipsec profile AZURE-PROFILE, tunnel-group 40.115.49.202 type ipsec-l2l, tunnel-group 40.115.49.202 general-attributes, tunnel-group 40.115.49.202 ipsec-attributes, ikev2 local-authentication pre-shared-key supersecretpassword, ikev2 remote-authentication pre-shared-key supersecretpassword, route AZURE-VTI01 10.0.0.0 255.255.255.0 169.254.225.2 1, AZURE-VTI01 10.0.0.0 255.255.255.0 169.254.225.2 1. remote selector 0.0.0.0/0 255.255.255.255/65535 The purpose of this gateway_ip is to point traffic into the tunnel interface, but the particular gateway IP itself is not important. Ive not tested, but I have had some feedback where its suggested the ASA needs two outside IPs? dpd-link: on For further clarification, contact Microsoft Azure support. Description. Everything works when we initiate from inside the ASA, but when they initiate from outside the ASA in the Azure environment they are not able to reach the inside hosts? Required fields are marked *. For further clarification contact Microsoft Azure support. Click Ok on the Add Endpoint window. To test, you can configure a continuous ping from an inside client and configure a packet capture on ASA to verify it is received: capture [cap-name] interface [if-name] match [protocol] [src-ip] [src-mask] [dest-ip] [dest-mask]. Azure currently restricts what Internet Key Exchange (IKE) version you are able to configure based upon the VPN selected method. local-gateway: 2.2.2.2:4500 (static) end Our local subnet is 10.1.0.0/22. Step 8. As shown in the diagram above, Policy-Based VPNs are used to build Site-to-Site and Hub-and-Spoke VPN and also remote access VPNs using an IPSEC Client. This command allow for Outside interface talk to net resources in Azure but this wont work for me. If your network is live, ensure that you understand the potential impact of any command. Ensure that the VPN traffic is not subjected to any other NAT rule. That's all we need to configure, please remember the phase-1 and phase-2 parameters should match on both sides for a successful VPN connection. Microsoft Article: Said 9.2 or above RichardjGreen: Said 8.4 or above it: Said 9.8.2 (tested) backgroud: my tunnel was working without tunnel interface with a different internet link. To enable this connectivity, your on-premises policy-based VPN devices must support IKEv2 to connect to the Azure route-based VPN gateways. Most of our employees use standard VPN client connections to the ASA. As time flies by, ASA is now able to terminate route-based VPN tunnels (which is great! set pfs group21 Learn more about how Cisco is using Inclusive Language. The problem is that when Azure happens to Initiate the tunnel, traffic selectors get defined that only permit the first of the two address spaces to traverse the tunnel. In the Azure portal. So that is why it doesn't need an explicit route. Create the remote traffic selector object. Cisco ASA firewalls are usually used as border network devices connecting the Enterprise network with the ISP and hence the Internet. If ENCRYPT:DROP seen in packet-tracer. Step 2: Configuring a VPN policy on Site B Cisco ASA Firewall Step 3: How to test this scenario. Cisco ASA - routing traffic between multiple site-to-site tunnels Ask Question Asked 10 years, 8 months ago Modified 10 years, 8 months ago Viewed 6k times 1 We have a Cisco ASA providing multiple site tunnels to our clients. group 21 24 Run debugs to view the tunnel negotiation process and identify where and if a failure occurs. I have a slightly complex challenge scenario I would like to ask you about. Note: The phase 1 IKEv1 attributes listed are provided best effort from this publicly available Microsoft document. Configured Site to Site IPsec VPN tunnels to peer with different clients and each of client having different specifications of Phase 1 and Phase 2 policies using Cisco ASA 5500 series firewalls. remote-gateway: 1.1.1.1:4500 (static) Maybe I just have to shift the way I think about VPN tunnels to Azure. Great article. Step 1. This article contains a configuration example of a site-to-site, route-based VPN between a Juniper Networks SRX and Cisco ASA device. auto-negotiate: disable Many small offices moves their serwers to cloud. Sign int0 Azure > All Services > Resource Groups > Create Resource Group > Give your Resource Group a name, and select a location > Create. Fullikev2 debug procedure and analysis can be foundhere. If reply traffic from Azure is seen, then the VPN is properly built and sends/receives traffic. Without the completion of this step, ASA with crypto maps fails to establish the connection due to a mismatch in the traffic selectors received from Azure. Configure the ISAKMP policy or Phase 1 parameters with the creation of a new one. Cisco Firewall Service Enterprise Router Modules, Cards & Adapters . Remember that a Cisco ASA firewall is by default capable to support IPSEC VPN but a Cisco Router must have the proper IOS software type in order to support encrypted VPN tunnels. Its so dirty haha. Click Save . tunnel protection ipsec profile ipsec-prop-vpn, crypto ipsec ikev2 ipsec-proposal AES-256-GCM To summarize from the ASA and FTD configuration perspective: Cisco recommends that you have knowledge of these topics: The information in this document is based on these software and hardware versions: The information in this document was created from the devices in a specific lab environment. Step 3. Equipment Used in this LAB: ASA 5510 - Cisco Adaptive Security Appliance Software Version 8.0 (3) Cisco Router 2801 - C2801-ADVIPSERVICESK9-M Version 12.4 (9)T4 Scenario: ip address 169.254.0.249 255.255.255.252 Procedure: To manually configure a VPN Policy using IKE with Preshared Secret, follow the steps below: The below screen shot of SonicWall with basic configuration LAN and WAN. Now let's see a brief description of each VPN Type. ????? Step 7. On the FMC dashboard, click Deploy at the top-right pane, choose the FTD device, and click Deploy . Theres No ACL to Allow the Traffic, or an Interesting Traffic ACL? Four packets are sent and four are received over the IPSec SA with no errors. You are using 169.254.225.0/30 on ASA and 10.0.200.0/29 on the Azure end. For a site-to-site IKEv1 VPN from ASA to Azure, follow the next ASA configuration. Please note that these policies should match on both sides. Step 14. dpd: on-demand/negotiated idle: 20000ms retry: 3 count: 0 Create a tunnel group under the IPsec attributes and configure the peer IP address and the IKEv2 local and remote tunnel pre-shared key: Step 7. In this example, the traffic of interest is the traffic from the tunnel that is sourced from the 10.2.2.0 subnet to 10.1.1.0. The advantage of Easy VPN is that you don't have to worry about all the IPSEC security details on the client side. It is not recommended to have a wide-open ACL such as the one in this example in production environments. nat traversal mode: keep-alive interval: 10 inbound ForFTD, further information on how to configure VTIs can be found here; For IKEv2 route-based VPN that uses VTI on ASA: ASA code version 9.8(1) or later. Back on the Network Objects window, add your new remote object to the Selected Networks section and click OK . Also, verify the output-interface is correct - it must be either the physical interface where the crypto map is applied or the virtual tunnel interface. On the command-line interface, the VPN configuration looks the same as the one for ASA devices. config vpn ipsec phase2-interface (And I work for a cloud provider, (that isnt Azure!)). It finds a match and then knows it needs to send the packet in a tunnel to the remote peer 195.17.10.10. This routing statement is placed in the routing table of the firewall/router such as any other static/dynamic/connected routes. after reconfiguring Azure all broken. This document describes the concepts and configuration for a VPN between CiscoASA and Cisco Secure Firewall and Microsoft Azure Cloud Services. SK_er: 39671dc0e37b947a-35f0b35484c15f94-77af132ef506b74f-c30b21411f907312-f2f09a3a Tom. Step 18. This supports route based VPN with IPsec profiles attached to each end of the tunnel. version: 2 If ike-common debugs show the crypto process is triggered, debug the IKE configured version to view tunnel negotiation messages and identify where the failure occurs in tunnel-building with Azure. config system interface Configure a crypto map and apply it to the outside interface, which contains these components: The peer IP address The defined access list that contains the traffic of interest The IKEv2 phase 2 IPSec Proposal The phase 2 IPSec lifetime in seconds An optional Perfect Forward Secrecy (PFS) setting, which creates a new pair of Diffie-Hellman keys that are used in order to protect the data (both sides must be PFS-enabled before Phase 2 comes up)Microsoft has published information that conflicts with regard to the particular phase 2 IPSeclifetime and PFSattributes used by Azure. Can be used with Cisco ASA OS (pre 8.4) IKEv1 only. ikev2 local-authentication pre-shared-key *****, Session-id:71467, Status:UP-ACTIVE, IKE count:1, CHILD count:1, Tunnel-id Local Remote Status Role SHA-1 or MD5 are considered weak and not recommended to use in a production environment. On the Node A section click the green plus button to add a new one. Finally create the VPN > Select your Virtual Network Gateway > Connections > Add. Verify no NAT translation occurs on the VPN traffic. The next step is to create a tunnel interface and attach the proposal we created in the previous step. There are a few ASA commands that you can use to verify the tunnel status. name: KG-Main Not sure about whether later version supports OSPF or EIGRP. On the same window, click on the green plus button to add a new ISAKMP policy. Step 2. The attributes listed are provided best effort fromthis publicly available Microsoft document. These cookies do not store any personal information. next The information that conflicts phase 2 IPSecattribute from Microsoft isvisible here. set dhgrp 21 In this blog post, we will go through the steps required to configure IKEv2 tunnel-based VPN on the ASA firewalls. An optional PFS setting, which creates a new pair of Diffie-Hellman keys that are used in order to protect the data (both sides must be PFS-enabled before Phase 2 comes up), can be enabled via the use of this configuration: crypto map outside_map 20 set pfs . The phase 2 IPSec lifetimes set are based upon publicly available Azure documentation. On the Network Objects window, click on the green plus button next to the Available Networks text to create a new object. next For further clarification, contact Microsoft Azure support. In that case would you still need to use SLA to alter the route or would the interface go down with a loss of connectivity to Azure and fail down to the next higher cost route? Reason being we want servers to go through our network to log in/outgg traffic to the internet. lifetime/rekey: 86400/85677 proposal: aes256gcm Many Enterprises utilize two ISP connections for redundancy and for bandwidth efficiency reasons. peer-auth: no It can contain multiple entries if there are multiple subnets involved between the sites.In Versions 8.4 and later, objects or object groups can be created that serve as containers for the networks, subnets, host IP addresses, or multiple objects. Personally Id use an SLA, but you go with what you know! It is set up same as yours not sure what is going on here. https://www.petenetlive.com/KB/Article/0000951, https://www.petenetlive.com/KB/Article/0000040. tunnel source interface outside You also have the option to opt-out of these cookies. Back on the IPSec tab, configure the desired Lifetime Duration and Size. The sample requires that ASA devices use the IKEv2 policy with access-list-based configurations, not VTI-based. Cisco 9500 StackWise Virtual Configuration, Site-to-Site VPN between Palo Alto and Cisco ASA, Cisco ASA Active/Passive Failover Configuration Example. Do you write articles on scripting for cisco hardware using Python? For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. As mentioned above, you might want to turn the firewalls off to test. It is mandatory to procure user consent prior to running these cookies on your website. All Services > Virtual Networks > Create Virtual Network > Give the Virtual Network a name, a subnet, select your resource group > Then create a Subnet, give it a name and a subnet > Create. Let's start with our new task - creating our first VM and setting it up for future use. As a reminder, Oracle provides different configurations based on the ASA software: 9.7.1 or newer: Route-based configuration (this topic) 8.5 to 9.7.0: Policy-based configuration !!!!! The attributes listed are provided best effort from, . Encr: AES-GCM, keysize: 256, Hash: N/A, DH Grp:21, Auth sign: PSK, Auth verify: PSK > Select your Resource Group > OK. Im using 9.9(2)36, VTIs are supported on 9.7, but as with all new things, Id assume that was buggy and go for 9.8 or above. IPSec Local and remote traffic selectors are set to 0.0.0.0. The ASA VPN module is enhanced with a new logical interface called Virtual Tunnel Interface (VTI), used to represent a VPN tunnel to a peer. The complex part is that I would like to maintain the current route through the WAN link as a backup path in case the tunnel from the branch fails, keeping in mind that the tunnel with the main office would still have the same summarized networks for the branches subnets, and that the tunnel with a specific branch would have just the subnet for that branch in its encryption domain. set proposal aes256gcm As we know, there is no preemption in IPsec site-to-site VPN on Cisco ASA to the primary peer. However, you have to set the IP address on the tunnel interface manually after that. Overview ;(. So where is 169.254.225.2 assign to? Fullikev1 debug procedure and analysis can be foundhere. Create a new IPsec proposal. addr: 2.2.2.2:4500 -> 1.1.1.1:4500 > Select your Resource Group > OK. Configure the Cisco ASA for 'Policy Based' Azure VPN Their purpose is to set things globally, and are generally hidden from the config, (i.e show run wont show them). config ipv6 Configure the crypto map and apply it to the outside interface, which has these components: The peer IP address The defined access list that contains the traffic of interest The TS The configuration does not set Perfect Forward Secrecy (PFS) since publicly available Azure documentation states that PFS is disabled for IKEv1 in Azure. More than 6 years ago (!) You can check whether there are any policies by running show run crypto ikev2 command. Specify the name of the policy and choose the desired Encryption, Hash, Diffie-Hellman Group, Lifetime, and Authentication Method, and click Save . Create a NAT exemption rule: Note:When multiple subnets are used, you must create object groups with all of the source and destination subnets and use them in the NAT rule. Step 11. Ideally, you want to use the strongest authentication and encryption algorithms the peer can support. set src-name all the zone commands <- can be omitted if you arent using zones), or via classical CLI commands: (The ACL is omitted. rx packets: 0 bytes: 0 errors: 0 Let's connect to R1 and start the configuration . tunnel mode ipsec ipv4 Step 5. One inbound SA with SPI 0x9B60EDC5 and one outbound SA with SPI 0x8E7A2E12 are installed as expected. Logic says that Azure VPN Gateway subnet and subnet on which VTI is on should be the same. Configuring Site-to-Site IPSec IKEv2 and IKEv1 VPN On a Single Cisco ASA Firewalls Running IOS - Studocu configuring ipsec ikev2 and ikev1 vpn on single cisco asa firewalls running ios version overview in the previous article you have seen how to configure ipsec DismissTry Ask an Expert Ask an Expert Sign inRegister Sign inRegister Home All of the devices used in this document started with a cleared (default) configuration. Connect to the ASAand create a set of IPSec and IKEv2 proposals. We're setting up a VPN link to a 3rd party provider (a financial clearing broker) that uses a Cisco ASA on the other side in order to exchange trade clearing messages via FIX protocol (a TCP-based protocol for financial transactions). VPN tunnel is not yet established but is in negotiation. set dst-addr-type name Enable IKEv2 on the outside interface: Note:Microsoft has published information that conflicts with regards to the particular IKEv2 phase 1encryption, integrity, and lifetime attributes used by Azure. On the Create New VPN Topology window, navigate to the Node B section and click the green plus button to add the remote endpoint traffic selector. . set vdom root Receive notifications of new posts by email. There are two methods to define the VPN encryption domains: route-based or policy-based traffic selectors. But it is, a valid IP on the subnet that My VTI is in, so the firewall will route traffic Down the Tunnel to try and get to it, and the static route statement sends traffic destined to Azure to that address, so it will emerge within the Azure virtual Network gateway, ready to be routed to the correct destination address, after the packets enter the virtual tunnel 169.254.x.x is not needed any more. First of all let's apply some good practice config's to make this tunnel a little more stable and perform better. The sample requires that ASA devices use the IKEv2 policy with access-list-based configurations, not VTI-based. Phase 2 IPSecattribute information from Microsoft that conflicts is. ), And some screenshots from the ASA: (the third one showing the logs after a manual logout), PS: Sorry for being legacy IP only this time. This is the configuration that will allow you to define the pre-shared key with the particular remote peers. R1#conf t Enter configuration commands, one per line. Choose the Encryption Domain/Traffic Selectors/Protected Networks. You can also verify that datapasses over the tunnel through a check of the vpn-sessiondb l2l entries: Bytes Tx: and Bytes Rx: show sent and received data counters over the IPSec SA. For additional configuration examples, see KB28861 - Examples - Configuring site-to-site VPNs between SRX and Cisco ASA . Step 6. Let's assume the client-pc (172.16.10.25) in the branch office needs to access a web server (192.168.10.10) in the headquarter and we need to set up a VPN tunnel to provide connectivity. Route-based IPSec uses an encryption domain with the following values: Source IP address: Any (0.0.0.0/0) Destination IP address: Any (0.0.0.0/0) Protocol: IPv4 If you need to be more specific, you can use a single summary route for your encryption domain values instead of a default route. Ensure that there are no access-list drops seen. Sending 5, 100-byte ICMP Echos to 169.254.0.250, timeout is 2 seconds: Check your inbox and click the link.

Thank you for this article, one question. Just one question. I have a question though. When ill try set up AAA Radius server in ASA, in interface section is no VTI interface on list. Note:Microsoft has published information that conflicts with regards to the particular IKEv2 phase 1encryption, integrity, and lifetime attributes used by Azure. Create an access list that defines the traffic to be encrypted and tunneled. Policy-based local traffic selectors and remote traffic selectors identify what traffic to encrypt over IPSec. (Azure must be configured for policy-based VPN. First of all, I will create the ISKMP Phase 1 policy for remote router R1. Step 17. This means that if IKEv2 is used, then route-based in Azure must be selected and ASA must use a VTI, butif the ASA only supports crypto maps due to code version, then Azure must be configured for route-based with policy-based traffic selectors. direction: responder That is a good question, I would use reverse route injection on all the smaller sites, so if the tunnel is up, they will use their WAN connection, then have static routes at each site with a higher metric/cost pointing to the WAN connection at the main site. enc: aes-gc 469ec9f9ab955145fcbf4861bd31a7008c41ab2178df03eb23cd1cd4658cbc4b50c1abf0 It can contain multiple entries if there are multiple subnets involved between the sites.In Versions 8.4 and later, objects or object groups can be created that serve as containers for the networks, subnets, host IP addresses, or multiple objects. Select Cisco ASA 3DES/AES License in the Product list, and click Next. You can now use TLS 1.3 to encrypt remote access VPN connections. IKEv2 attribute information from Microsoft that conflicts isvisible here. Our ultimate goal here is to set up a site-to-site VPN between the Branch Office and the Headquarters. No policy maintenance Unlike Policy-based VPN, there will be no policy maintenance in Route-based VPN. Configure route-based VPN tunnel on Cisco ASA In this article we explain how to configure a basic route-based site-2-site VPN tunnel Nenad Karlovcec Jun 3, 2022 2 min read Route-based tunnels are preferred when creating a site-to-site VPN tunnel to Azure. set net-device disable You've successfully subscribed to Packetswitch. This is an expected condition when you first bring the tunnel up. Route-based VPN allows determination of interesting traffic to be encrypted or sent over VPN tunnel and use traffic routing instead of policy/access-list as in Policy-based or Crypto-map based VPN. I have connection to this machine from on-premise LAN. Im sure! I attempted using ASA to set it up but ran into issues so reverted it back to policy-based VPN. Step 10. These were typically used with routers, because routers usedVirtual Tunnel Interfaces to terminate VPN tunnels, that way traffic can be routed down various different tunnels based on a destination, (which can be looked up in a routing table). spi: 8185487b On the Create New VPN Topology window you can see now both nodes with their correct traffic selectors/protected networks. Cisco ASA now supports Virtual Tunnels Interfaces (After version 9.7(1)). NO (Unless you were hair pinning a traditional VPN from another ASA into this tunnel, or an AnyConnect client VPN session.). The last thing to do, is tell the firewall to route the traffic for Azure though the VTI.Note: The last octet in the destination IP is different from the VTI IP! Packetswitch Suresh Vina. Step 1. edit KG-Main A collection of articles focusing on Networking, Cloud and Automation. I have set few routed VPNs to Azure using other solutions such as Cisco routers and Palo Altos. This website uses cookies to improve your experience while you navigate through the website. Can be used on older Cisco Firewalls (ASA 5505, 5510, 5520, 5550, 5585). The encryption domain is set to encrypt only specific IP ranges for both source and destination. Other than that, they do not show up in routing and cannot be accessed. Step 2. In this post I will cover all the steps necessary to install ESXi on your computer, Configure Policy-Based and Route-Based VPN from ASA and FTD to Microsoft Azure. No, Ive never attempted to do what you propose, though I can see the obvious requirement for doing so. I am using a Fortinet FortiWiFi FWF-61E with FortiOS v6.2.5 build1142 (GA) and a Cisco ASA 5515 with version 9.12(3)12 and ASDM 7.14(1). e1831416107c6ca5c1d6da624269ba4e21b7d45c95d5a16da8c0f9200b598ebbab76f5b9, 3d6e5ab8c1ac1de02a230095d76778dd5b88aeeff7dfae8b25df26c265bdec56710d040e, # show crypto ipsec sa peer 194.247.4.10 detail, #pkts encaps: 29, #pkts encrypt: 29, #pkts digest: 29, #pkts decaps: 45, #pkts decrypt: 45, #pkts verify: 45, #pkts compressed: 0, #pkts decompressed: 0, #pkts not compressed: 29, #pkts comp failed: 0, #pkts decomp failed: 0, #pre-frag successes: 0, #pre-frag failures: 0, #fragments created: 0, #PMTUs sent: 0, #PMTUs rcvd: 0, #decapsulated frgs needing reassembly: 0, #Valid ICMP Errors rcvd: 0, #Invalid ICMP Errors rcvd: 0, #pkts no sa (send): 0, #pkts invalid sa (rcv): 0, #pkts encaps failed (send): 0, #pkts decaps failed (rcv): 0, #pkts invalid prot (rcv): 0, #pkts verify failed: 0, #pkts invalid identity (rcv): 0, #pkts invalid len (rcv): 4009213712, #pkts invalid ip version (send): 0, #pkts invalid ip version (rcv): 0, #pkts invalid len (send): 0, #pkts invalid len (rcv): 0, #pkts invalid ctx (send): 0, #pkts invalid ctx (rcv): 0, #pkts invalid ifc (send): 0, #pkts invalid ifc (rcv): 0, #pkts failed (send): 0, #pkts failed (rcv): 0, #pkts replay rollover (send): 0, #pkts replay rollover (rcv): 0, #pkts min mtu frag failed (send): 0, #pkts bad frag offset (rcv): 0, #pkts internal err (send): 0, #pkts internal err (rcv): 0, Route-Based VPN Tunnel FortiGate Cisco ASA.

Encryption domain for policy-based tunnels The drawback of this method is that you for instance can't run a routing protocol between the two VPN peers, because you don't have interfaces on which the routing protocol can be associated. NAT exempt does not match when I choose outside physical interface as outgoing interface. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product. We also need to add a static route that points to the tunnel to reach the remote subnet. Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. Step 6. All Services > Local Security Gateway > Create Local Security Gateway > Name it > Supply the public IP > Supply the Subnet(s) behind the ASA > Select your Resource Group > Create. Here, an IKEv1 SA built with ASA as the initiator to peer IP 192.168.2.2 with a leftover lifetime of 86388 seconds is shown.

It was a long-due release especially if you are working with multi-vendor VPNs. The interface configuration is self-explanatory, ASA has two interfaces, one for the Server and another one for the Internet. This is accomplished in the Azure portal via PowerShell script deployment to implement an option that Microsoft calls UsePolicyBasedTrafficSelectors as explained here: https://docs.microsoft.com/en-us/azure/vpn-gateway/vpn-gateway-connect-multiple-policybased-rm-ps.
