I wasn't sure if this is the right forum for this. It is an RVS4000, but I've had similiar problems with the WRT55AGv1 and WRT55AGv2. I was thinking its about time I just ask: The background details: 192.168.100.0/24 network, server at 192.168.100.1, router at 192.168.100.100. 192.168.99.0/24 VPN network (not using the VPN feature of the router, I wanted a VPN that runs as a service, plus I trust the security of OpenVPN more). There is a route sent to the router via RIPv1, 192.168.99.0 255.255.255.0 192.168.100.1 LAN. It is not set static because when I did that the server was unable to access the internet (I'll assume this part doesn't make sense to you either). The server only sends the 192.168.99.0 route, and ignores all incoming routes. The problem is computers on the VPN cannot communicate properly with the computers on the LAN. I believe the problem lies with the router (this same problem occurs with the WRT55AGv1, and WRT55AGv2). The VPN computers can communicate with the server, the router, and the printer (this part was strange... I'm guessing it listens to RIP, maybe for SNMP purposes). When a route is added to the computers (route add 192.168.99.0 mask 255.255.255.0 192.168.100.1), the computers can communicate. Without the route, the computers should be sending to the default gateway (the router), correct? This is why I believe the router may be the problem, but I may just be missing something here... was hoping someone would have an idea.
