Nowadays, the 2 major gaming console types used extensively around the globe are, NAT stands for Network Address Translation, which represents the ability to translate a public IP address to a private IP address, and vice versa. NAT Traversal is a UDP encapsulation which allows traffic to get the specified destination when a device does not have a public address. If the source ports remains the same (depends upon application where a specific source port may be require) the translation type is Dynamic NAT, which will preserve the clients source port per translation. 666426. I am here to share my knowledge and experience in the field of networking with the goal being - "The more you share, the more you learn.". NAT-T is a method of assigning Public IP address and encountering problem when data protected by IPsec passes through a NAT device and changes to the IP address cause IKE to discard packets.
