Two Networks - Similar Scopes

I've got to physical networks. Alpha is setup with 10.2.16.x scheme and Bravo is setup with 10.0.1.x scheme.

Both have 255.255.255.0 subnet mask.

I have one xp machine that needs to be on both networks. How do I accomplish this?

on the one machine that needs to be on both networks, add a second NIC, set the networks as you would normally for the 2nd network but only one of the NICs should have a gateway. Put the gateway on the NIC that has the best network access or only access to the internet.

When you say that XP machine needs to be in both networks, do you mean it needs to be reachable by both networks or has to be physically connected to both networks?

It has to be able to reach another machine/servers on both networks.

Commented:
you can do this by just routing between the two networks and if only that machine needs to reach the server then you can create ACLs to limit access.

If you need more help on how to set this up please post a network diagram, and state what brand and model router and switches you have in your network.

ah, you are trying to route traffic using the XP? Any specific reason the switches aren't directly connected?

Well, take a look at this link about using an XP machine to route traffic.

You were correct. I had a bad NIC when I was testing the first time that is why I thought it wasn't working. Thanks
