Due to a recent breach on my system I`m now tightening up the security of my server.
I have setup IP tables and I want default action to REJECT except for my listed rules.
This works for the HTTPS rule, for the IMAP rule, etc. But it is not working for my HTTP / port 80 rule.
I checked apache config and apache should be running on port 80. I also did netstat -tulpn | grep :80 to find out port 80 was being used by apache. This was the exact output:
netstat -tulpn | grep :80 tcp6 0 0 :::80 :::* LISTEN 5902/apache2
Anyone experienced the same issues? I was thinking maybe I was locked out by fail2ban or something, but no rules from fail2ban at the moment, also when navigating to the site from another IP it still does not work..
