[TriLUG] Internet connection Sharing

[Chris Bullock]

I am tring to set up Internet connection sharing for my 
home network.  Hardware, Using a Compaq deskpro with dual 
nics, one compaq and one smc1211.  Have broadband coming 
in from my modem to eth0 which is my compaq card.  eth1 
(SMC)card is going to a Netgear 4-port 10mb hub which will 
hopefully feed my internal machines.  I am using Mandrake 
9.0 with all the updates.  I have tried this twice on two 
different machines with the same result.  I goto Mandrake 
Control Center and click Internet connection sharing and 
go through the steps, download the needed packages and so 
on, Configure my eth0 as the Internet interface and my 
eth1 as the LAN interface.  All seems well until it 
finishes configuring.  At this point my eth0 (Internet if) 
goes down. No light on the card or the modem.  service 
network start will not bring up external interface.  
ifconfig does not show external but does show the 
internal.  What file(s) does the Internet connection file 
use so maybe I can look at to see anything that stands 
out?  Or can someone help? 
 
Thanks in advance,
