[SLE] Need help with Simple IP Masquerading

Ok, I've done my best to get this working over the last few days. And I
know I'm missing something really obvious.

The SuSE box dials up my ISP fine, and Internet access works fine from this
box. The Win98 box can access the SuSE box without a problem.

At this point all I want is masquerading -- the Win98 box on the internal
network should have full access to the SuSE box services, too.

I get this in /var/log/messages when trying to access an external web site
via the Win98 PC (the Win98 is 192.168.0.98).
