iptables

Hi,

My server is Red Hat Enterprise Linux Server release 5.

I'm not an expert in Linux iptables firewall.

After installation, I find the following entries in /etc/sysconfig/iptables.

*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -j ACCEPT
-A FORWARD -j ACCEPT
-A OUTPUT -j ACCEPT
COMMIT

What does this iptable filter restriction rule mean?
