Re: Firewall blocking my new Debian 11 server ports 80 and 443

[IL Ka <kazakevichilya@gmail.com>]

I am running an Apache server and using Qualys Lab’s server checker. It shows no access to the server.

Have you tried to telnet to port 80 from home? Do you see apache listening this port using ``ss``?

 

Whatever attempt I make to change the ports disappears when I reboot.

Sure, because you need netfilter-persistent (at least for iptables)
