Newbie question....

[Emmanuel Calatan]

Hello,
     I'm a newbie with linux
and I'm trying to install a firewall using redhat 7.1
using iptables. 

My firewall can already ping every host in the
internal LAN and in the internet but my host in the
internal LAN can't ping the internet. What is my
problem?

The firewall is already set to allow ip_forwarding.
I checked the file /proc/sys/net/ipv4/ip_forward and
it was set to "1".

The routing table looks fine to me. it has a default
gateway with both interface

I set the iptable rules to allow everything just for
my testing.

I already disabled the default firewall from the
intallation. 


Thanks in advance...
