Hi Gary,
This is really relatively easy.
First make sure you do have network continuity between your machines.
Second configure each win98 machine to have a gateway address of the Linux box.
Third turn on Ip Forwarding in the Network Config.
Forth configure the IP Fordwarding/Masq.
I have pasted a copy of the ipfwadm that I use on boot up. Maybe it will
give you some idea.
