EDIT: No one got any ideas? It's definately an ISA quirk.

Hi everyone, first time posting on this forum so hello.

I currently have an IPSEC Site to Site VPN setup between a Checkpoint UTM-1 and ISA 2004 which will only work correctly if I have both a Route and NAT network rules setup on the ISA between the VPN Network and the Internal Network. I've set the Checkpoint to Bypass NAT when going through the VPN tunnel but if I remove the NAT rule from ISA, the VPN Clients can no longer browse the internal network, if I remove the Route rule, the Internal Clients can't see the VPN Clients. Does anyone have any idea why this would be the case?

Thanks in advance for any help you can give me.

Regards

Barry
