How to push my own DNS server to OpenVPN?

view story

http://serverfault.com – I have defined an ubnound DNS server on my VPS and it appears to work. I need to use the DNS server instead of Public DNS IPs because some ISPs have blocked public DNS IPs. My openvpn.conf file is: dev tun proto tcp # Notice: here I set the listening port to be 80 to avoid possible port blockage port 80 ca /etc/openvpn/easy-rsa/2.0/keys/ca.crt cert /etc/openvpn/easy-rsa/2.0/keys/server.crt key /etc/openvpn/easy-rsa/2.0/keys/server.key dh /etc/openvpn/easy-rsa/2.0/keys/dh1024.pem user nobody group nogroup server persist (HowTos)
