As from january 2005 the IPSec NAT-T solution is fully standarized by the IETF IPSec Working Group and published as the RFC's 3947 Negotiation of NAT-Traversal in the IKE and 3948 UDP Encapsulation of IPsec Packets. This is an important milestone to remove the last barrier to fully deploy the IPSec protocol in a client-to-gateway VPN scenario.

I've updated my article accordingly. Also, it is a pity that the two excellent Microsoft Technet Webcasts "IPsec and NAT-T : Finally in Harmony? (Level 400)" and "Demystifying IPsec (Level 400)" given by Steve Riley are no longer available on the Microsoft Webcast site. However, on Steve Riley's website you should be able to find the excellent powerpoint presentation IPsec and NAT: Finally in harmony.

For more information, check out the full article How to pass IPSec traffic through ISA Server.
