Recently, I have a problem with my CentOS server. I’ve apache server (this is on port 80), cannot access from another remote location..  For solving the problem I checked the iptables.

I enable access that blocking the port  80 on iptables.

I type the command :

[code]sudo /sbin/iptables -I INPUT -p tcp -m tcp –dport 80 -j ACCEPT[/code]

And then save the iptables by using the command :

[code]sudo /sbin/service iptables save[/code]
