DNS "Leak" with .ovpn Linux

[irishtechnomonster 1]

My understanding is that only Windows is susceptible to DNS leaks but my Raspbian system with openvpn using the config files generated here is showing my ISPs DNS server on ipleak.net and dnsleaktest.com. How can I fix this?

 

I've tried adding 

dhcp-option DNS 10.4.0.1

 

to the config file but it doesn't make a difference.

 

Any idea how I can solve this?

Check the resolv.conf

 

/etc/resolv.conf

nameserver 10.5.0.1

nameserver 10.4.0.1
