[TriLUG] Routing/router questions from a network wannabe :-)

[J.C. Jones]

All,

I have a Verizon Broadband card ( EVDO ) that works great with Ubuntu, 
Red Hat 9.0, and Fedora Core 5 on my laptop. I would like to create a 
system within my laptop that would hook to the internet through the EVDO 
card ( in the pc/pcmcia card slot on my laptop ) and use a usb- ethernet 
adapter to provide a internet connection to other users within a small 
network.

Since these are two different networks (usb-ethernet is 192.168.x.x. 
where EVDO is dynamically assigned IP address from verizon ) and 
different types of adapters ( usb-ethernet is eth0 and the EVDO card is 
ppp0 ) ,  I don't know how to pass traffice from one adapter to the other.

Can someone point me to a plain and SIMPLE instruction set or howto that 
would enlighten me on  what to do?? I am not sure whether I should be 
working with the route tables, iptables, a combination of the two --- Or 
something totally different.

I would prefer using Fedora Core 5 for this project, but if it is easier 
to accomplish with something different, I am game.

Thanks for your input.
