OpenVPN Support Forum

Hi everyone,

I am trying to filter which dns request goes to the dns server over the vpn and which dns request goes to the internet and I wondered if it is somehow possible with OpenVPN.
All the domains which should go over the vpn have a specific naming convention and could be determined via regex.

Thanks in advance.

Not sure what you mean. You're either using the DNS provided by your VPN carrier or one of your choosing. If you see two separate DNS requests you have a leak.

Are you using the update resolve script with --up in your config?
And if so, have you installed resolvconf to update your /etc/resolved.conf?
