Hi guys, I'm having a bit of a prob. I'm hoping is easy to resolve.  I
finally got my cablemodem on Saturday (w00 h00!).  Well, I can get out fine
with my linux box.  I'm trying to set my girlfriends windos machine up to
get internet via my linux box/cablemodem.

Background:
a) linux box gets out(internet) fine on eth1; DHCP, gets DNS from provider,
etc.
b) win box is connected to linux box on eth0 (via hub)
c) win box has linux box set as gateway machine.
d) win box has static ip assigned to it.
e) win box has DNS set same as linux box's DNS
f) IP_FORWARD = YES is set in /etc/sysconfig/network on linux box
g) win box can ping linux box(eth0) fine.
h) win box CAN'T get internet via hostname _or_ IP addy.
i) default route on linux box is ISP/CABLEMODEM;

what am I doing wrong?  Do i need a route for the 192.168 (internal) net to
send packets over to the 24.88.(external) interface?  I thought forwarding
would did this...  My kernel is 2.4;

My routing table has:
  my external network 	(24.88.22.0) 	eth1
  my internal network 	(192.168.0.0) 	eth0
  my loopback 		(127.0.0.0) 	lo
  my default gw 		(24.88.22.1) 	eth1

If anyone needs any more info, I can gladly provide it.  I'm at my wits end
on this, and I fear that I've done something stupid that I just can't see.

If anyone can provide me with any leads, I would greatly appreciate it!!!

TIA,
CB
