I have a similar setup at my house.  I am using kernel 2.0.20 and
ipfwadm (http://www.xos.nl/linux/ipfwadm).  This web page was enough
for me to set up my own firewall rules from the example.  I am at work
and cannot access my home box, but I would be glad to post my firewall
script (I call it in /etc/rc.d/rc.ipfwadm).

Check out the "paper" (http://www.xos.nl/linux/ipfwadm/paper/
for the examples.

Note:
I found that a 386 box can not handle a 28.8 modem and ipfwadm.
I would recomend at lease a 486/25 for the "gateway" box.
