DNS Redirection & Host Override

[The Computer Guy]

I'd like to force DNS redirection using the Netgate Document online.

https://docs.netgate.com/pfsense/en/latest/recipes/dns-redirect.html

But also need a Host Override in place for HTTPS Redirection.

Ideally I would like to force the DNS through DNS servers other than the DNS servers used for the firewall, as the portal traffic will be passed through to SafeDNS, any suggestions?

I've come up with a solution (I hope!)

I've created a subdomain on the domain that I have a wildcard certificate for. This is set to the IP address of the interface. i.e portalabc.domain.co.uk > 192.168.200.1

I'm not really fussed about anyone trying to visit portalabc.domain.co.uk outside of the network.

I did notice though, using either the DNS Forwarder or Resolver on the admin LAN, I have to add it as a host override, otherwise ping returns "host not found" for a subdomain pointing to an rfc 1819 IP.

Is this setup likely to cause issue somewhere?
