recently I had to troubleshoot my openvpn configuration. I need to add that I had a running configuration for many month and I changed nothing on my server. But suddenly I experience some strange "read UDPv4 [EHOSTUNREACH]: No route to host (code=113)" messages so I tried to narrow it down further. And by doing this I noticed that my server can't ping any domain. This is no good, is it? Maybe I should start here... Like I said I changed nothing on my running system. I run Ubuntu Server 11.10. What can I do to solve this?
Any hints are highly apreciated.
