iptables question

[Blackburn, Marvin]

I'm trying to get familiar with iptables.  I am making some progress,
but I'm trying to figure out what these lines mean in
/etc/sysconfig/iptables (especially the first 5).

This was generated on a rhel5 system using system-config-securitylevel

 

*filter

:INPUT ACCEPT [0:0]

:FORWARD ACCEPT [0:0]

:OUTPUT ACCEPT [0:0]

:RH-Firewall-1-INPUT - [0:0]

-A INPUT -j RH-Firewall-1-INPUT

-A FORWARD -j RH-Firewall-1-INPUT

-A RH-Firewall-1-INPUT -i lo -j ACCEPT

COMMIT
