Synology DNS: loopback multiple domains to NAS?

[TokyoHam]

So after much trial and error, I managed to set up three WordPress container sites on my NAS, with reverse proxy for each so the sites are accessible from outside my network at DOMAIN1.com, DOMAIN2.com and DOMAIN3.com. Unfortunately, I cannot connect to those URLs from within my network, only from outside.

My router (Orbi RBR50v1) supposedly supports NAT Loopback, but there is no way to configure it in Settings, so either their KB article is in error, or the feature is missing in current firmware.

Since I can't do it on my router, I decided to use Synology DNS server to loopback those domains to my NAS, but apparently you can only have ONE reverse zone per destination IP address. Since my NAS is hosting all three websites with a single IP address (using reverse proxy for each domain) it seems there's no way to actually accomplish this. Does anyone know of any solutions/workarounds?

setup up a local DNS server and point DOMAIN1.com, DOMAIN2.com and DOMAIN3.com to your Synology IP.
I am doing this with a Pi-Hole docker container which is with MACVLAN setup and its own IP instead of a port

Then on the DHCP server I am giving the Pi-Hole IP for DNS and for static IPs like my Synology I am giving manually for DNS my Pi-Hole address

Hope that is working for you.
