iptables problems

[Scott Queen <scott_queen yahoo com>]

Problem 1:
RH Linux 7.2, kernel 2.4.9-34, iptables 1.2.4  (potential
incompatability based on some sources)
I have a RH Linux box acting as a firewall/router.  It is connected to
ATT HOME on the internet side; a network with two Win98 pcs on the LAN
side.  I have successfully connected to that ATT HOME network with the
linux box (can ping www.yahoo.com, can surf the web from the linux
box).  I can ping a network pc from the linux box, can ping the linux
box from the network pc, but I cannot ping the internet from the
network pc.  I have a very basic iptables configuration in the
rc.firewall file.  What do I need to do to be able to ping the internet
from the network pc?  (it looks like the network pc is getting the
correct ip address of the internet sites I'm trying to ping, so I think
DNS, gateway, etc. ip's are working.

Problem 2:
I read that there is an incompatibility between kernels 2.4.9 and
iptables 1.2.4.  So - I downloaded the patch to upgrade from iptables
1.2.4 to 1.2.5.  However - my linux box does not have a patch command
on it, so I don't know how to apply the patch.  Is this a problem with
my Linux? (can you tell I'm new to Linux???)

Thanks,
Scott Queen
