I’ve never used CasaOS, so I can’t help you with that, but I run NetBird for remote access to my homelab. What you’re describing sounds to me like an issue I used to have with Tailscale.
I think NetBird might be trying to route your traffic through a STUN/TURN server to get around a NAT or firewall. A NAT (in case you haven’t heard of it) is a sort of “mapping” from one IPv4 address to many IPv4 addresses. Its used to "make more "addresses, otherwise we would have run out decades ago. (this is a simplification, its actually much more complicated)
The first thing to check here is: Are you behind a CG-NAT? (there’s probably some websites to check this)
If yes, then there is little you can do without setting up a VPS to get around it.
If that’s not it, then you’ll have to figure out how CasaOS handles networking internally. Your services might be behind a NAT inside.
As for ressources/information, I mostly stuck to the official docs.

There are a lot of concepts that you mention which I don’t understand at all. I’ll look into each one of them and once I can understand what you’re refeering to exactly I’ll check what you said. Thanks a lot :D
