Hi
I have problems with connection WinXP l2tp ipsec
client to Linux 2.6.6 with racoon.
In case the NAT isn't between client and server
everything is ok but when client is behind NAT occurs broblems with
connecition.
I applied WinXP update ( L2TP/PISec NAT-t update)
and racoon is configure with NAT-T. On my server my firewall have open ports for
ISKMP ( 500 ), L2TP (1701), and NAT-T (4500) and permits peckets of
ESP protocol.
When I applied tcpdump on server interface there
are any packets on 4500 port ( NAT-T) only on port 500. The key negotiation ends
on phase1.
Have somebody the same problem??Know somebody the
solution of this problem.
Thanks and sorry for my English!!
Best regards
Tomek
