[SOLVED] OpenVPN doesn't work

Hey,

I got 'config.ovpn' from my VPN provider and try to connect with standard command 'openvpn --config config.ovpn' but problem is that it just doesn't work.
I actually make connection (I think), it updates ip routing and sometimes I can actually access internet for 2-3sec and see that my IP is VPN's IP.
But after that when trying to visit some site it doesn't say that there is no network connection but instead browser just tries to connect, for ever.

Couple words about how I connect to internet. I don't have router and my computer is plugged to socket in wall VIA lan cable and I DHCP client and gateway is ISP's router which is located at somewhere in house (dunno what connection this is, heard somewhere that's broadband?).

'IP route' before VPN connection:

Code:

default via 60.192.60.1 dev eth0 
60.192.60.0/19 dev eth0  proto kernel  scope link  src 60.192.77.245 
127.0.0.0/8 dev lo  scope link

'IP route' after VPN connection:

Code:

0.0.0.0/1 via 5.44.18.1 dev tun0 
default via 60.192.60.1 dev eth0 
5.44.18.0/21 dev tun0  proto kernel  scope link  src 5.44.18.125 
46.55.9.11 via 60.192.60.1 dev eth0 
60.192.60.0/19 dev eth0  proto kernel  scope link  src 60.192.60.245 
127.0.0.0/8 dev lo  scope link 
128.0.0.0/1 via 5.5.8.1 dev tun0

Also there are actually few errors in during connection, but not sure are they root of this problem:

Code:

 
 [OpenVPN_Server] Peer Connection Initiated with 46.55.9.11:1194
 SENT CONTROL [OpenVPN_Server]: 'PUSH_REQUEST' (status=1)

Which operating system you are using? Do you have the latest version of Opevpn? If not then try to upgrade it and see.

Thanks!

Solved.
Problem was with DNS resolving and was able to fix it with couple changes in '/etc/resolv.conf'. Feel so stupid, had my ISP nameservers in 'resolv.conf' and guess they accept only resolving from customer IP's -- since VPN isn't customer of this provider it failed to resolve URL addresses I tried to access, realized it when pinged (for no particular reason) some random IP successfully but still wasn't able access URLs.
