 Using Multiple NIC's In The Same PC. Confused.
I will be building a cisco lab soon and I have question about multiple NIC's in a single PC.
I plan on adding an additional NIC to my PC with the idea of having one NIC connected to the lab for the purpose of ping/telent/etc. and the other NIC connected to my cable modem and the internet.
See my attached drawing for a visual depiction. Sorry for the quality. I ain't no Picasso.
My question is when I pull up a command prompt and issue a ping then how does Windows know which NIC to direct the ping to?

You would set up that pc to run as a gateway. The nic the moedem is attached to will have the external IP and the nic connected to the lab you will have to setup with a network address.
I suggest connecting the first router to the NIC then connect the second router via serial, then use the ethernet port on the second router to connect the cisco switch.
Here's a diagram.

Wouldn't it be better to go from the modem to one router ethernet port then use NAT/PAT to go to the rest??? I was going to dom that actually but an IOS I was trying to install was giving me errors...
