Whee! That works. Figures -- three obnoxious "gurus" told me
that I was wasting my time on masq & that I needed route, "Only
routed will allow you to route the packets through the Linux box
to the W98. I wonder, though, why can't I ping the Linux box
from W98 now?

Hmm. Wonder where I did that. Know what file I'd edit --
there have been so many I've opened & some I've edited, though
only one today ifcfg-eth0:1.

If you mean to change the line in the eth0:1 file from 10.0.0.2
to 10.0.0/24 I then bring eth0 down then up I get:
# /sbin/ifup eth0
/etc/sysconfig/network-scripts/ifup-aliases:
ipseen_10_0_0_0/24=ifcfg-eth0:1: No such file or directory
error in ifcfg-eth0:1: already seen ipaddr 10.0.0.0/24 in /24
