Split DNS for Route10

Hi team,

Im a new Route10 user and would like to see if we can explore a possibility of adding split dns as a feature.

I typically have a regular internet DNS that all quereies will go to but i would like to use an internal DNS server for only a specific domain - i.e. all DNS queries from example.internal will go to (an internal DNS resolver) 10.x.x.15 while the rest will go out to (ISP provided DNS server) 8.8.8.8

It would be really useful for homelab users!

I’m not using a Route10 to test but maybe the port-forwarding rules can be used. I do something similar on my pfsense box.

Create an outbound rule to catch all DNS queries to WAN from the host or subnet you want to redirect and have that rule forward that traffic to your 10.x.x.15. This will be harder with DoH as it runs on port 443 but maybe they will improve the firewall filters to include DoH blocking at some point.

Not really what we want to achieve here as we can just set DNS via DHCP for the target subnet here anyways

The main goal is to send out all DNS over the regular DNS channels (ISP, Google, Cloudflare, etc) and only my own domains over to my internal DNS servers over a wiregaurd connection.
