When using Cyberghost through OpenVPN, my computer still uses the DNS settings from my router (in this case, Google Public DNS). I was able to use OpenVPN without DNS leaks on Ubuntu 15.04.

Following this article: http://www.ubuntubuzz.com/2015/09/how-to-fix-openvpn-dns-leak-in-linux.html

I don't have a DNS leak if I connect to my VPN via terminal. But if I connect via Network Manager, I still have a DNS leak.

Is there a known way to fix this, or is it a bug with Network Manager? If I can't fix it, can my ISP still track me if I'm not using their DNS servers?

If it helps, here's my OpenVPN configuration:

remote 4-us.cg-dialup.net 443
dev tun 
proto udp

resolv-retry infinite 
redirect-gateway def1
cipher AES-256-CBC
auth MD5
ping 5
ping-exit 60
explicit-exit-notify 2
script-security 2
remote-cert-tls server
route-delay 5
tun-mtu 1500 
fragment 1300
mssfix 1300
verb 4

ca ca.crt

cert client.crt

key client.key

script-security 2
up /etc/openvpn/update-resolv-conf
down /etc/openvpn/update-resolv-conf
  • How often do you use your VPN? You could set your gateway to be a route only to your VPN IP, thus forcing all traffic to use your VPN or be ignored Dec 10, 2015 at 1:08
  • If the dns connection to Google is unencrypted then your isp can read all your traffic to it...

  • @WilhelmErasmus I don't use VPN very often on my computer (mainly on my phone). If I set my VPN as the gateway, will I still be able to log in correctly? Dec 11, 2015 at 0:24
  • In that case it won't work. It'll only work if you always use your VPN on your computer. Dec 11, 2015 at 0:58
  • Please edit your question to include the output of route -n when you are connected via network-manager and terminal. Dec 11, 2015 at 0:59

There is an open bug for this issue: https://bugs.launchpad.net/ubuntu/+source/openvpn/+bug/1211110

  • I found this listing as well after I did some more searching. The only problem is that it hasn't been assigned to anyone yet. I hope it gets fixed soon. Dec 11, 2015 at 20:29
  • @SuperSluether Me too for your part. Good luck ;) You could make an alias for the connection to ease its use. Dec 11, 2015 at 21:20
  • And enjoy the new rep ;) Dec 11, 2015 at 21:21
