Try this:
ipchains -P forward DENY
ipchains -A forward -s 192.168.0.0/24 -d 0.0.0.0/0 -j MASQ

> # ipchains -P DENY
> # ipchains -A forward  -s ppp0 -j MASQ

And try not to set a defaultroute for LinuxBox prior to ppp connection
... not sure how you end up with this routing table ...

How about some output/setting from Win98 (ie. dns setting, gateway ...),
try a trace from the Win98 instead ...
