Hello, If this is on a container, containers cannot run the firewalls. You need to have some form of an ingress controller maybe nginx in front or HA Proxy that will do the filtering for your containers.

It seems that: image: lscr.io/linuxserver/fail2ban<https://link.edgepilot.com/s/28ed2e1a/Lb4p6m44qE2AsTB_wreyXQ?u=http://lscr.io/linuxserver/fail2ban> is using Alpine linux and doesn't come with firewalld, but that doesn't make any sense. I asked on the list in case anyone knew. Perhaps its because Alpine doesn't support systemd, but surely I can't be the first person that ran into this..
