[Vpn-help] How does NAT-T really works?

[Stefan Bauer]

Hi Matthew,

i'm still confused, how nat-t really works. I've seen setups, where a
single client can made up roadwarrior connections to his company
through a nat without nat-t. Is there any _good!_ and _easy_
documentation how a ipsec association works with nat-t? I'm looking
for something detailed like:

Client sends first package with destination-port 500 to ipsec-server.
ipsec server answers to package ....

Probably you get this questions asked often, but i'm really trying to
understand this in principle. I appreciate your help.

Thanks
