NAT-T
Encyclopedia : N : NA : NAT : NAT-T
NAT-T (NAT-Traversal in the IKE) is a mechanism in IPsec for UDP encapsulation of the ESP packets in order to better go through firewalls. The negotiation during the IKE (Internet key exchange) phase is defined in RFC 3947 and the UDP encapsulation itself is defined in RFC 3948.
This capability exists in Windows XP SP2 but must be [enabled].
