Hey fedi 
Does anyone know a good opensource firewall for a Linux server with an admin panel in web or tui?

I want to see recent tcp & udp connections, preferrably some info about their contents (e.g. compute JA4 fingerprint for TLS, extract domain from DNS request) and be able to immediately block by source/dest IP subnet, ASN, geoip, maybe even by JA4.

I guess i can just google it but i want to hear your recommendations. Firewall is a high-privileged software that have to be trusted anyway.

Thank you

Found it too, but if i get it right, it's a separate system like openwrt or opnsense, so i have to add one more server to my infra or run it in qemu
