Your right, it shouldnt matter at all how you are connected to the
net, be it via a modem or other device.  I initialise all my ip
forwarding/masqing before i have any connection to the outside world
at all on bootup (modem hasnt dialed) and as soon as that link goes up
the masqing works great.

Something to check is if you are using one of the very first options
when compiling the kernal when it asks if you want to use
'experimental, blah' drivers.  I got caught on this the first time too
as it looks like you are adding everything into the kernal for
forwarding/masquerading but you are missing things and it wont work if
you forget this 1st option.

Once you have the kernal right I use this to setup forwarding in my 
boot time:

ipfw-on:

#!/bin/sh
ipfwadm -F -p deny
ipfwadm -F -a m -S 192.168.1.0/24 -D 0.0.0.0/0


Have you also thought about getting 2.0.29 or higher kernal and using
that as it has a LOT of the patches installed and shouldnt give you
trouble.

I had trouble use the ipfw tool under slackware linux 1.2.13 as there
was some code in the original source that didnt allow proper
forwarding/masqing but with a 2.x kernal you should be right.

Failing the above, i would strongly suggest you get the latest kernal
2.0.31? and install that EXACTLY as outlined in the masquerading FAQ
and ill go hop if it wont work :)...
