I have modified a building network to be PABP compliant (Visa) where two router and two subnets are required.
My original building network configuration was set-up to enable remote access to a terminal server via port forwarding on an RVS4000 router. Thus cable modem -> wan xx.xx.xx.xx ROUTER lan 192.168.1.1 -> Subnet 192.168.1.0 with Port Forwarding TCP 3389 to 192.168.1.11 (terminal server).
The new network configuration is composed of two RVS4000 routers on two subnets. Thus Cable Modem -> wan xx.xx.xx.xx ROUTER1 lan 192.168.2.2 -> Subnet 192.168.2.0 -> DMZ 192.168.2.14 and second router wan 192.168.2.1 ROUTER2 lan 192.168.1.1 -> Subnet 192.168.1.0.
Router1 is configured in gateway mode and Router2 is configured in router mode. Port forwarding on Router1 for TCP port 3389 is to 192.168.2.1 (wan port on Router2). Where as port forwarding on Router 2 for TCP port 3389 is to 192.168.1.11 (terminal server address).
With this new network configuration I am no longer able to connect to the Terminal Server remotely. No problem gaining access to the Internet and subnet 192.168.2.0 from inside subnet 192.168.1.0.
Thus I think my problem is port forwarding through the two RVS4000 routers. Any assistance with this problem will be much appreciated.
