I have 3 networks. Networks A and B are local, and attached to an ASA firewall and are operating as desired. Network C is remote, and is connected to network A through a PIX firewall VPN, and is also operating normally. The issue is that network B cannot communicate with network C through the VPN tunnel that is established. From network A, I can ping all devices on network B and C, which is good. From network B, I can ping devices on network A and only the outside public interface of the remote PIX connected to network C, nothing inside. From network C, I can ping devices on network A but only the ASA interface connected to network B, nothing inside network B interface.
While in network C, I need to be able to address all devices on networks A and B and vice versa. By virtue of the ability to ping the interface of network B, it appears that the ping traffic is going up the VPN tunnel, so I am at a loss to explain why devices on network B cannot communicate to network C and vice versa. Bottom line is that I need traffic from all 3 networks to freely pass all interfaces, which is occurring between networks A and B, and A and C, but not B and C. What am I missing? I can share firewall configs if necessary..
