Hi, I have the following scenario:
NET 1 is 192.168.1.x
DCHP Server/Gateway is a Linksys Box

Because the linksys box is running out of ip leases.

One cheap solution is isolate 20 computers creating another NET 2 192.168.2.x

Right now we have two PDCs in NET1. The second PDC is serving 20 computers.

If i install a second NIC and DHCP Server into the PDC#2 so the second NIC can lease ip addresses with scheme 192.168.2.x part.

How can make the 20 computers go out to the internet?
What kind of settings do i have to type in the NICs in PDC#2?
Do I have to enable IP Forwarding?

Thanks for ur cooperation

If your net1 is your outlet to the internet on your dhcp server for net2 setup a default gateway to net1 the gateway will be provided to these 20 computer when they receive their ip from the dhcp server

Although I am not familar with routing I think If you set the subnet in the dhcp to 255.255.0.0
the 192.168.1.x and the 192.168.2.x should be able to see each other and thus both should be able to see the gateway.

Install two NICs in an NT server.
Install the Routing and Remote Access service.
Enable IP forwarding.
Configure the gateway on the 192.168.2.x NIC card with the address of the 192.168.1.x NIC (This tells computers on your 192.168.2.x how to get to the other network).
Set the gateway on the 192.168.1.x NIC to the address of your Linksys box.
Add a persistent route statement to the server with two NICs:
c:\route -p add 192.168.2.0 mask 255.255.225.0 192.168.2.x (x being the address of the servers NIC)
This statement will tell the server to route all traffic addressed to the 192.168.2.0 network back through the NIC instead of the Linksys.
