Hi all,
       I have four computers on a home network. Internet connectivity
is supplied via an ADSL router with ip address 192.168.0.1 and is used
as default gateway by all computers.One is my music and video file
server running linux, two others run Windows XP and the last is on
Windows 98. All five network devices (including ADSL router) hook up to
a 100Mbps switch. I recently obtained a 10Mbps hub an two extra NICs. I
wanted to hook up this hub downstairs, thereby allowing me to place an
additional computer there, but unfortunately, the wiring was carried
out only for one computer therefore, there is only one cable going down
and I do no not wish to put one of my XP machines on a slower network.
So I got the idea that I will attach a second NIC to the XP machine,
and connect the hub to that and then distribute a network through that.
My problem, as you may have guessed now, is how do I get these two
networks to communicate with each other? I have already enabled the
IPRouterEnabled setting in the registry, but I do not have the
knowledge to proceed an further as routing tables confuse me a great
deal. The IP addresses are as follows:

192.168.0.1 - ADSL Router
192.168.0.2 - Upstairs XP machine
192.168.0.3(100Mbps)/192.168.1.1(10Mbps) - Downstairs XP machine
(switched on 24/7 as it is my downloading machine)
192.168.0.4 - Linux media server
192.168.1.5 - Windows 98 machine which has migrated downstairs

the 0 subnetwork is on the 100Mbps switch, while the 1 subnetwork
should exist on the 10Mbps hub.

Any help that could be offered would be recieved most gratefully

Thank you.
