24.1 Production Series / Re: Enabling dnsmasq and unbound on port 53 BUT separate interface = issue ?
« on: May 04, 2024, 03:29:18 pm »
2 DNS server needs 2 different ports
unbound 53
dnsmas 54(assuming unused)
then you create rule in your firewall in one of your lan segment 2
1) to accept port 54
2) a port forward lan segment 2 address dns to firewall port 54
you run 2 dns server on different port, 1 of your lan segment will then portforward dns query to your secondary dns server.
this works as I am doing it, 1 dns for local lan and 1 dns for wifi
you can run 2 dns on same firewal using the same port
