I have two routers. One is a main router that is connected to the internet, one is being used as a VPN connection. I don't want all my computers to be on the VPN, just some media computers. The setup is working great, but the problem is my computers on the VPN network can't access the computers on the main network. Is there any way I can make that happen? I know if I disable the VPN and just leave the router as a DHCP I can access the network resources without any problems. Here's a diagram of the setup:
I - Internet
A - Main router and connection to internet
B - VPN router
C1 & C2 - computers on main network
C3 & C4 - computers on VPN network
In a nutshell I want C3 to be able to access C1 without having to move it between networks. I was thinking of using a computer as a bridge and connect it to both networks, but I rather not go out and get a computer just for that. Another alternative I was thinking about is to connect C1 to the VPN, but wouldn't that mean that when I transfer from C1 to C3 it has to go through the internet and come back into the network?
Sorry about the poor & confusing explanation.
Just as more information, C3 and C4 are media centers, android devices and NAS enclosures. C1 and c2 are computers but they are too far away from my routers for me to pop in an extra NIC and link the two networks together. Also I am looking for a solution where I don't have to leave a computer on 24/7.
