VPN trough a Cisco 761 ISDN router possible?

[gvanderhave]

Can anybody tell me if it is possible to set up a VPN with a Cisco VPN Client for Windows and a PIX Firewall trough an (old) Cisco 761 ISDN router?

Yes you can just make sure you are using NAT translation not Port translation.

Actually the is not enough memory to support in the 700 series routers to support a full Blown IPSEC tunnel, If that is what you are looking for try terminating the tunnel to an 800 series ISDN router. You may be able to terminate GRE with 700 though.
