I have setup an OpenVPN server on my linux box using a tutorial that I found online. It works, as in clients can connect and get assigned and IP address but I am unable to ping between the client and server or the server and client. I am a bit of a newbie when it comes to networking put I'm guessing it has something to do with the server not being able to route back to the client.
Here is my setup
Server on network 172.16.0.0 255.255.255.0
Server has network bridge
Server ifconfig output
