Connecting two networks together by having two network cards in the same computer

[Surfrat]

Hi,

I recently aquired two 100Mbs cards and I am trying to incorporate
them in my existing
network at home. My old network looks as follows:

10Mbs 10Mbs
Mountainman ------------- Surfrat --------
Win XP Win 98SE |
192.168.0.1 192.168.0.2 |
255.255.255.0 255.255.255.0 |
|
|---------------------------------------------|
|
| 10Mbs
|- Jukebox ---------------- Jukebox 2
Win 98SE Win 98SE
192.168.0.3 192.168.0.5
255.255.255.0 255.255.255.0


I have installed the two 100Mbs cards into Mountainman and
Surfrat as follows:


100Mbs
Mountainman -------- Surfrat
Win XP Win 98SE
192.168.0.1 192.168.0.20 (100 Mbs card)
255.255.255.0 255.255.255.0(100 Mbs card)
192.168.0.2 (100 Mbs card gateway)
10Mbs
192.168.0.2 (10 Mbs card) ----------|
255.255.255.0(10 Mbs card) |
192.168.0.20 (10 Mbs card gateway) |
|
|------------------------------------------------------------|
|
| 10Mbs
| -- Jukebox ---------------- Jukebox 2
Win 98SE Win 98SE
192.168.0.3 192.168.0.5
255.255.255.0 255.255.255.0


The result of this is that the 10Mbs network can all see each other.
Mountainman
can only see Surfrat and not the others.
Surfrat cannot see Mountainman.

Please help me to configure this so all the PC's can see each other.

Thanks

SurfRat.

If I understand your diagram, Surfrat has two network cards with IP
addresses in the same subnet. That's bound to cause problems, because
Surfrat will only be able to use one of the cards. That's why it can
only see the 10Mbs computers.

You could assign the two network cards to different subnets (e.g.
192.168.0.x and 192.168.1.x), but you'd also need to run routing
software on Surfrat and create LMHOSTS files on all of the other
computers to define the mapping of computer names to IP addresses
across the subnets.

A better solution is to move the 10Mbs network card from Surfrat to
Mountainman and create a network bridge on Mountainman. That will
combine the two physical networks into one logical network, with one
subnet, allowing all of the computers to access each other. I've
written a web page with details:
