I need to connect to openVPN server from Ubuntu 12.04 installation.

So, I've installed network-manager-openvpn package and configure vpn connection.

Then I try to connect to vpn server, see success message but when I try to do something with network get the "Destination is unreachable" error, so I can't even ping the vpn server.

This is the client.conf file I got from server

client
dev tun
proto tcp
remote server.com 1194
nobind
persist-key
persist-tun
ca ca.crt
cert igor.crt
key igor.key
comp-lzo
verb 3

In network manager settings I set the gateway (server.com), Auth type - Certificate (TLS), set all certificates, enable Use LZO data compression option and Use TCP connection. So, what may be wrong or where I can find some logs?

I had the same set up with Ubuntu 11.10 and it was worked fine, so it's definitely something missing in my configuration.

Thanks in advise.

UPD: When I run openvpn --config client.con vpn works fine

ifconfig when vpn is connected but not working

I had probably the same problem. I found different 2 solutions searching the web.

  1. Go to IPv4 setting->Routes and check the "Use this connection only..." . [This did not work for me]

  2. The other is to specify a DNS: Go to IPv4, change the Method to "Automatic (VPN) addresses only" , and specify a DNS (for example Google's 8.8.8.8) [Worked for me]
