IPSec VPN - crazy problem
----------
Hi all,
if been wirking for days now on this problem, maybe you could help ?

Thats the Situation:
Netw.1)
2 Win2003 Servers, 1 NAS & 1 DC,Exch,ISA Server
Int. IP NW: 192.168.1.0
Ext. IP Addr.: 83.64.x.x

Netw. 2)
Lancom Router
several Clients
Int. IP NW: 102.168.0.0
Ext. IP Addr.: 83.65.x.x

IPSec Tunnel uses Des-MD5 Encr.

The tunnel works fine if it is initiated fom the Lancom side.
Connection from NW1 to NW2 is only possible from the NAS Server and not the ISA Server.

The trace on the Lancom router shows an Phase 2 error stating that no Enc. could be selected for the IDs (83.64.x.x <-> 192.168.0.0).
I guess the Problem is, that the ISA Server is using its external IP Addr. for the connection, and not the internal.

I have no Idea how to fix this.
