ANSWERED openvpn not display websites on linux

[Guest user1984]

Hi,

 

On windows 8, home computer, all is OK, airvpn good speed... but...

On laptop linux (arch), sometime some websites display slowly (google), but most websites does not display.

(Its the same line, internet box, ISP)

 

I try with various protocols and various ports (udp 443, tcp 443 ...53) but nothing...

 

My config file :

 

client
dev tun
proto udp
remote earth.vpn.airdns.org 53
resolv-retry infinite
nobind
ns-cert-type server
cipher AES-256-CBC
comp-lzo
verb 3
explicit-exit-notify 5
ca "etc/openvpn/ca.crt"
cert "etc/openvpn/user.crt"
key "etc/openvpn/user.key"

 

I lauched openvpn :

 

# openvpn /etc/openvpn/airvpn_UDP_53.ovpn

Hello,

 

it seems just a DNS problem. Please check that while connected to the VPN server your system /etc/resolv.conf file includes the line:

 

nameserver 10.4.0.1

 

Please see here for more details on OpenVPN DNS push on various Linux systems:

https://airvpn.org/topic/9608-how-to-accept-dns-push-on-linux-systems-with-resolvconf/

 

Kind regards

/etc/resolv.conf file includes the line:

 

nameserver 10.4.0.1

 

The problem is solved.

 

Thanks !
