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.

Holy shit, this is what it looked like!? I saw the wikipedia article posted recently, and was wondering if there where any pictures.

The article only specifies “makeshift composite armor plating”, which made me think it was just some steel plates.

But no wonder over 200 rounds of ammunition and three explosions had no effect. No wonder they briefly considered using an airstrike or an anti-tank missile to stop it.

It also looks to me like he was always planning to die inside, I don’t see any way to get the shell off again.
