docs on NAT-T ?

[ctivig]

Hello,

Anyone has a good document which explains how NAT-T is working ? (not the basic NAT, but NAT-Transversal !)

If you can mail it at constantin.tivig@rogers.com or if you have a URL I would apreciate it a lot !

Thanks,

This is Windows XP related, but it should get you on the right track.

There isn't a ton to it - if both sides supports it, it gets negotiated via the isakmp process (udp 500), and then all the actual ipsec packets get wrapped in udp packets with destination port 4500.
