Having the exact same issue. However I made it one step farther. In my openvpn config text I added the following:
push "route 10.8.8.0 255.255.255.0"
(pushing my internal network)
This allowed me to surf the web (however laggy) where all my traffic is through the tunnel. I was also able to access interal web pages.
However testing with other apps such as mail and streaming services such as youtube is not working. Continuing to plug away.
