I have defined an unbound DNS server on my VPS and it appears to work. I need to use the DNS server instead of public DNS servers 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 10.8.0.0 255.255.255.0 persist-key persist-tun #status openvpn-status.log #verb 3 client-to-client push "redirect-gateway def1" #pushing public DNS IPs push "dhcp-option DNS 126.96.36.199" push "dhcp-option DNS 188.8.131.52" comp-lzo
As it is suggested here, I tried to use my server's IPs (say 184.108.40.206). So instead of
push "dhcp-option DNS 220.127.116.11" push "dhcp-option DNS 18.104.22.168"
I just put
push "dhcp-option DNS 22.214.171.124"
In openvpn.conf above. However, after restarting openvpn, I see that my client can still connect to the OpenVPN server but no pages can be rendered anymore.
What can be wrong here? How can I solve this problem?
