How do I set up a dual nic server to get internet from existing network and use dhcp to serve a test network

We have just installed a new 2008 server with 2 nics and are setting up a test environment.  We would like to use 1 nic to get internet from the existing network and use the other nic to serve dhcp to the test network.

How do we set these nics up to do this?

create your DHCP scope for your internal network (test) network.

Nic 1 == 10.10.200.x
Nic 2 == 192.168.99.x

nw2 == / 24

dhcp scope created for

Not the solution you were looking for? Getting a personalized solution is easy.

Ask the Experts
yes, give two different subnets for 2 NICs and configure DHCP for only one NIC and scope for that subnet only. Don't  bridge these two NICs


Both solutions did help but in the end it was a matter of turning on ICS on the external nic that solved the problem

I don't care about the points (I'm lying like a dog :|- ) but I guess with you closing this question, I'd like to know if you could rephrase your question just as to what the problem was that required ICS... It doen't seem to be clearly spelled out in your question.



I have a new 2008 server with 2 nics.  We are setting it up in a test environment within an existing network. We need to keep this network separate from the existing network while using the internet connection.
1 nic was set up for an internal network(test network) and the external network (existing).  I wanted to know how to get internet access to the test network from the existing network.

Both replies gave instruction to create the 2 separate networks but did not address the need to share the internet connection from one network to another.  

This was solved by turning ICS on the external nic.

I have no issues splitting the points as both replies gave the same part of the answer but neither had the complete solution.

Again, i appreciate the responses.


Thank you for your responses.
