DNS Resolver, PPPoE, OpenVPN client (AirVPN) and outbound interface
I have an AirVPN configuration for all outbound traffic. I configured DNS resolver to forward requests to the AIRVPN (OpenVPN) interface. I also configured the general setup / dns servers to use that same airvpn interface as a gateway. All of this was working correctly when my ISP / WAN interface was DHCP.
I recently changed ISP, and using PPPOE now.
DNS resolver does not work or forward requests. Nslookup against my pfSense box fails (locally as well on pfSense diagnostics)
I can't seem to figure out what else needs to be adjusted for this to work, and the only change what that PPPOE.
Any help diagnosing this is greatly appreciated!
