CSF Firewall Situation

[DrWizzle]

I believe CSF firewall was donated to the open source community, there are a few projects but I believe the official project can be found here:

GitHub - Aetherinox/csf-firewall: ConfigServer Security & Firewall (CSF) - Robust linux iptables/nftables firewall & free ipset blocklist service.

ConfigServer Security & Firewall (CSF) - Robust linux iptables/nftables firewall & free ipset blocklist service. - Aetherinox/csf-firewall

If you want any further info on this popular fork, join his Discord channel. He's very responsive and helpful. There's a few guys there that know the ins and outs of it all so maybe pop across there for a quick chat? And always test it out on a non production server first with data that's not important, or a copy of something you'll be running.
