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?
Maybe Pivpn ? Yes, you’ll need a small raspberry Pi, but then you can have it run wireguard to access all your home server gear. And then you have the added feature of putting Pinhole on there as well. Works for me here.
I still need to find a “$35 Raspberry Pi” 🤣
