Win2k Preventing PC with two nics to do internal routing

Hi,

I have a situation in which I have a pc with two NICs. I want to be able to send data from one NIC through the network to the other NIC but windows is trying to be smart and does the routing internally and bypassing the network altogether. Is there a way to force this?
 
hehe "Windows is trying to be smart".

What are you trying to do exactly? It's pretty easy to force traffic out one NIC via the routing table but you'll paint yourself into a corner and not be able to get traffic back out the other one properly.

 
Hi,

I am trying to get the latency of a device the NICs are connected to. You can basically think of the DUT as a very format strict router. I want to be able to obtain the latency of a specific payload size (hence pinging is not an option) and so I need a universal clock to measure the time. I am using a perl scrip that binds the client socket to one NIC ip address and another script that binds the server socket to the other NIC ip address to transfer a file from one NIC to the other. I noticed that the result is almost instantaneous. After a little googling, I found out that windows (2k specifically in my case) sees that the same computer has the destination address and thus it bypasses the network and NIC altogether.
 
it should do this...

you need to rethink your testing stratagy to a workable IP routing solution. I am STILL not getting what you want. is the DUT the Win2K box, or device connected TO the win2K box?
