I am searching for a firewall for my self hosted services. It should be conpatible with docker, podman and native running services. I should block clients with to many fauled authentication attempts. It should also support blocklists and be as easy to configure as possible (and foss ofc). I took a short look at fail2ban, but the github docs are just lacking so much information that I was looking for (like how to configure it). CrowdSec lookes not foss enough for me.

Any recommendations? Maybe some fail2ban guide?

Isnt opnsense only for bsd? I am running linux.

opnsense is bsd based yes, you can either run it on it's own hardware in front of your server or you can run it as a virtual machine and passthrough your hosts network ports to it for WAN/LAN.
