Set up for packet filtering.

At the initial condition, the access to the web server is controlled. The following shows how to set up for access permission.

[root@xoonips-server ~]# vi /etc/sysconfig/iptables
Copy the line below.
-A RH-Firewall-l-INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
↓ Change the "22" in the line to "80".
-A RH-Firewall-l-INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
[root@xoonips-server ~]# /etc/init.d/iptables restart	← Restart the packet filtering software.
