Good to know. But does fail2ban require ipset?

No, but having several thousand rules is not convenient, so I prefer ipset

They never have before in over 15 years, and, before I got this server started, its mate was serving fine. But if the ufw doesn't work, I'll ask them.

I'd start by switching to legacy iptables and running ``iptables -L -v -n``.
