In the past I have used OpenVPN a couple of times for a standard client to server setup (so-called roadwarrior).
Now I need to use a VPN for connecting two different office of my company. My idea is that each office has its own gateway to Internet, and the LAN traffic like if it was a single LAN, so that a user in an office can
transparently access a server in the other office.
I'm trying to avoid the installation of an OpenVPN Client in each computer / server. Instead I'm using OpenWRT routers to create the tunnel. The setup should be similar to this:
Is it even possible?
Anyone has done it before?
I think it's possible with some routing table "hackery", but I'm not sure how to.
