[vpn-help] win2008r2 ike phase 1 fails, works on win7x64 sp1

[Forster Martin]

Hi,

on a windows 2008 R2 Server i have a problem in phase 1.
Problem: the vpn client does not see the answers from vpn server.
I have verified with Network sniffer that the packets arrive on the win2008 r2 box.

The cap files from debugging are completely empty.
No send and no receivepackets.
In the iked log I see resend's and then a timeout like that:
