What is the purpose of NAT-T?

  • enables NAT for PC-based VPN clients
  • permits VPN to work when NAT is being used on one or both ends of the VPN
  • upgrades NAT for IPv4
  • allows NAT to be used for IPv6 addresses

Explanation: Establishing a VPN between two sites has been a challenge when NAT is involved at either end of the tunnel. The enhanced version of original IKE, IKE version 2, now supports NAT-T. NAT-T has the ability to encapsulate ESP packets inside UDP so that the VPN tunnel can be established through a device that has NAT enabled.
