Hi, I have such a network:
192.168.212.0/24 --[ Cisco 831 Router A ]--Internal Network-- [192.168.212.1 192.100.80.100] [ Cisco 831 Router B] ---- [ Firewall ] ---- 192.168.129.0/24 [203.x.x.18 172.x.x.133] 172.x.x.134 192.168.129.1]I set up a VPN link between Rouer A and Router B. From 192.168.212.5, I can ping 172.x.x.134 without any problem. I can also prove the traffic pass through VPN by using traceroute. I can also ping from
192.168.129.5 to 172.x.x.133. However, when I try to ping 192.168.129.1 from 192.168.212.5, it is never reachable. By using tcpdump, I can tell the traffic doesn't go through the VPN link. Rather, it goes through Internal Network, and never reach the firewall.How can I route all traffic to 192.168.129.0 through the VPN link, so that it can reach the firewall? Do I need to do something in Router A? Is VPN Routing and forwarding the way to go?
Thank you very much.
