We have a branch office in another country which has a ASA 5510 installed between their LAN and an internet router that connects to the local ISP. We're trying to create a tunnel to connect this branch office back to the Headoffice. At the headoffice we have a PIX 515E ver 6.3(4) installed between the LAN and the internet router. Both offices are on the same network but different subnet addresses.
So far we can ping the outside interface of the remote branch firewall but we can't access the inside network. Pls help.
