jails Running minecraft bedrock server in ubuntu jail

[einsibjani]

I setup a Ubuntu 22.04 jail using bastille: ` bastille create -L minecraft jammy 192.168.1.85`

Installed libcurl4 and fetched latest minecraft bedrock server.

When I try running the server with `./bedrock_server` I get this output:

According to socktat, the port is not in use, and changing the ports has no effect, so I guess bedrock server is using something to detect if the port is in use, or binding to it in a way that a jail doesn't allow.

I've seen posts about people having success running bedrock server in a chrooted ubuntu env on FreeBSD, so it looks like a problem with jails, not freebsd.
Any ideas what I can try to get it to work?
