openVPN

I have openVPN working (client-to-server). The server is openSUSE 11.0 and is the internet gateway. I can ping the servers internal ip from the client, but cannot ping machines on the internal network.

In the server config file I am pushing the route for the internal network. I have IP forwarding enabled.

tcpdump of tun0 shows the ping requests, but no replies from internal network. What am I missing?

arpproxy enable?
