I would like to be able to extend multiple networks between different physical locations without having to run a separate VPN connection for each network. Here's my example:
VPN Network is 192.168.1.0/24 using an OpenVPN server.
Assume 2 locations with the following setup: ASUS router running VPN client connected to 192.168.1.0. Has clients on 192.168.10.0/24 and 192.168.20.0/24.
I would like clients on both the 192.168.10.0/24 and 20.0/24 networks at each location to be able to talk to each other over the single VPN connection that is already established from the routers. Is this possible? Can someone point me to any relevant configuration options for OpenVPN? Perhaps I'm overthinking this and it's easier than it seems?
