I have installed CentOS 6 but I'm only able to open Apache2 to outside by turning off the firewall.
Can somebody give me a clue on how I can open apache2 to the outside without turning off the firewall?
UPDATE:
My iptables configuration is the following:
# Firewall configuration written by system-config-firewall
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT

This machine has the ip "192.168.59.142" and I need to access it the apache via another machine on my network.
UPDATE2:
The solution is to add this rule in "/etc/sysconfig/iptables" and then restart the iptables
-I INPUT -d 192.168.59.142 -p tcp --dport 80 -j ACCEPT
