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

I mean if you want to know who the bad guy is newsflash it's pretty much always the dude bombing hospitals and apartment buildings right? So you know, if that's a thing you do, you're not my friend and I oppose your works.

It's just people around me seem to be very keen to notice when it's our enemies doing the atrocities and not when it's us. Well I can't do that, my brain doesn't work that way.

I am against invasions. I am against hospital bombers. I am for apartment building dwellers.

NEW: CERT-EU accused cybercrime gang TeamPCP of being behind the recent European Commission hack.

It also accused ShinyHunters of being behind the leak of the stolen data, which was around 92 gigabytes, and contained full names, email addresses, and some email content.

It never gets old seeing what humanity can do with math and science while we continue to battle against our base instincts down here on Earth.
