www   ---   Firewall     ---     RH 7.3 box     ~~~     Win 98 laptop
                   10.0.0.1         10.0.0.5  10.0.1.1
10.0.1.38

If you are able to ping both interfaces of the RH7.3 "router" device
from the Win98 laptop, then the routing/forwarding piece appears to be
working.

When you ping something on the 10.0.0.X/24 network, does that machine
have a route entry for the 10.0.1.X/24 network?  Example:  If you have
another machine at 10.0.0.50, does it have a route to the 10.0.1.X/24
network pointing to 10.0.0.5?  I would guess that the packet is making
it to .50, but then .50 is sending the response via 10.0.0.1 rather than
10.0.0.5.

Depending on the other systems you have, you could use either Ethereal
or tcpdump on the 10.0.0.50 machine to see if it is seeing the traffic.
