connection between subnets

[Billyboy]

Hi,

I have two networks at home and I am trying to use a Windows 2000 SBS server
as a router to connect these 2 networks together. The Windows 2000 server
has 2 NIC's.

Network A uses real IP's 202.181.x.x with 255.255.0.0 as the subnet.
Windows 2000 server uses NIC 1 with an IP within this subnet.

Network B uses 192.168.0.x with subnet 255.255.255.0. Windows 2000 server
uses NIC2 with an IP within this subnet.

There are workstations on both sides of the subnet.

How do I set my workstations so that they can ping each other?

Thanks.

Peter

This is not a good idea. There are several problems.

1. One network is public, the other is private.
2. It is never a good idea to use your first/only DC as a router. Browsing
and name resolution may go crazy.
3. What will you do about DNS?
4. How will the machines in the 192.168.0 subnet get to the Internet?

I am just testing and not setting it up permanently.

Are you saying that this type of setup is impossible?

Thanks.

No. It is possible, but it usually causes more problems than it is worth.
You would be better off using some other machine or a hardware router to
connect the two subnets. Using a DC as a router causes all sorts of
problems.

How is your network set up at present? You will probably have to add
extra routing to your Internet router to prevent your private traffic trying
to use it as a gateway. eg

Internet
|
router
202.181.x.n
|
workstations
202.181.x.y dg 202.181.x.n
|
202.181.x.z dg 202.181.x.n
W2k server
192.168.0.1 dg blank
|
workstations
192.168.0.x dg 192.168.0.1

To get it to route, you would need to add a static route to the Internet
router to "bounce" the private traffic back to the Windows router. eg

192.168.0.0 255.255.255.0 202.181.x.z
