Superscopes & Routing

I have a Win2000 server set up as a router.

I want to set up a superscope with two nets on the same
physical network. For these two nets to communicate with
each other each must have a different gateway.

Can I just add the other network IP address to the TCP/IP
properties for the adapter so that the adapter has both IP
addresses related to the two scopes on the physical
network?

Will this work or is there something else I need to do?

Actually that is a "MultiNet", not a superscope -- but -- IF you
setup DHCP to support both of these nets then THAT is the
superscope.

DHCP superscopes support multinets.

Generally yes, but consider this:

If the two sets of clients try to communicate with each other, then
each packet will go to the router and back to the destination (on the
same wire) -- this is not a particularly efficient way to use a net but
it works.

You can also place "manual routers" on each set of machines to teach
them they don't need the (true) router to communicated.

Presume nets: 192.168.8.0/24, and 192.168.9.0/24
On each stations "x" of 192.168.8.x add this route:
route add 192.168.9.0 mask 255.255.255.0 192.168.8.x

On each stations "y" of 192.168.9.y add this route:
route add 192.168.8.0 mask 255.255.255.0 192.168.9.y

Substitute each machine (last octet) IP for .x or .y.

Another, simple choice is to just put another NIC in the router.
 
Hi,

Perhaps this article will help explan superscopes:
