Paulo... As Asterr suggested, you might have a iptable rules that are preventing data to go through. To clear those rules, try the following: Iptables -F Iptables -X Iptables -P INPUT ACCEPT Iptables -P OUTPUT ACCEPT Iptables -P FORWARD ACCEPT
The above wipes out any instance of any rules existing for the time being. If you restart the server, they'll appear again. In that case, disable iptables from starting by using chkconfig.
