IPTables: http / port 80 accepted rule not working, https rule is working

Hi,

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..

PS, I also tried with protocol UTP as well protocol TCP, where I think it should be TCP

Ok, drop this question. I`m now learning about IP tables and there is a lot more of concern like DNS etc. what is probably blocking me accessing the server.

It would be a nice thing if VirtualMin could provide a default set of rules to get things running btw.
