Block IP - web interface needed to make it?

Hey !
I see this forum topic How to block an ip?

There are many IPs in my Postfix daily summary Statistics mail server by Pflogsumm - Postfix
and I want to block those IP by hand definitely.
Fail2Ban may be doing the job for some a time, but I want to make it forever.
Now, I’m messing with iptables scripts not surviving a server reboot… I’ve to think about executing this script after a reboot… :confused:

It can be easiest to have something to do with the webinterface to add an IP, and an IP range /24 for example, to make it possible :slight_smile:

Many thx!
