Only route DNS traffic through VPN

ivant

Hello,
Can someone tell me if it is possible to configure the following:

1) Specify the DNS servers.
2) Only route the DNS Server traffic through the VPN. All other traffic would not use the VPN.
3) This is for mobile clients (iOS, Android) ipv4 and ipV6

Help would be greatly appreciated. Thank you.

I think the Ubuntu Server can help you. "iptables' rules" can restrict any traffic

That will only stop traffic once it hits the server ..
