[vpn-help] Peer 0.0.0.0

[Redoute]

Hello,

I want to configure Shrew VPN on a new Notebook with Windows 7/64:

A working configuration on Windows XP shows the IP of the UMTS 
connection (T-Mobile Germany, IP from a private range 10.x.x.x) as local 
address. Why does it fail on the new notebook? How is the peer IP 
determined?

Thanks in Advance, Redoute
