Apologies if this should be in Support. I felt it was a more general question than should go there, but I could be wrong.
I recently switched Internet Service Providers, and they gave me a new router. Several services on my FreedomBox began having issues. It seems this new router does not provide something called “NAT Loopback?” Basically, I can access my services from outside my network via my public domain name, but if I’m inside my network the public domain name doesn’t work, and I have to use a local IP address. So, if I’m at home and I try to access my Matrix server via a Riot app, it can’t find the server.
Is this an issue people run into often? Is there a simple way to fix this lack of NAT Loopback without purchasing a new router that has that functionality available?
