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

[Roper, Andrew]

Martin,

I'm a little confused. You say that a network sniffer sees that the packets are arriving on the Win2K8 server but the VPN client does not and that debug packet captures are empty. Where was the sniffer placed? Which debug packet captures are empty? What is the VPN server that you are trying to connect to? Is the Win2K8 server behind a firewall? Is it the same firewall that the Win7 box is behind? Are you using the same configuration file between the two machines? Are there any other VPN clients installed on the Win2K8 box? Is there a software firewall running (by default Windows firewall is on in Win2K8R2)?

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:

Any hints ?
