I have OpenVPN network with one server and two clients. When I setup my default route on C1 to go through S (which does have ip forwarding and NATing enabled), everything works as expected. The problem is, that if I point C1 default route to C2, (Which is also properly configured to NAT traffic from VPN to internet) the traffic gets snatched by S anyway and forwarded by it. When i tcpdump on C2, there is no sign of anything arriving there. Is it possible to setup client as gateway for other clients in OpenVPN or is it property of the system that packets get routed by server event if the route on client is pointed onto other client?
The square brackets represent my virtual network (it does not physically exist). C1/C2/S can ping each other within the network no problem. I want to route traffic from C1 through C2 to the internet. I can route from C1 (and probably from C2) through S to the internet but routing through C2 does not work as the packets get forwarded by S instead. This seems to be problem with the OpenVPN server not wanting to send packets where they should go.
