I am building a LAN to LAN from a cisco 3015 to a 2621. The 2621 will sit behind a firewall (one public interface and 2 private interfaces) on the far end. The 2621's public interface will have a translated address (static) from the firewall and will site on the firewalls one private interface. It's private interface will connect to a server. This server once creating traffic will create a tunnel through the 2621 and connect to a server behind the concentrator. My access-lists for IPSEC traffic will only permit traffic from the server behind the 2621 to the server behind the concentrator. What I want is to have communication from a server the other private interface of the firewall to talk to the server sitting on the private interface of the 2621 - is this possible??
