[H] VM second NIC

[Winterlight]

I have a new computer build = windows 8 PRO.  My PC motherboard has 
the usual 2 NICs. I want to install VMware version 9 workstation and 
have it use the second NIC. I have a three router network that 
isolates a WIFI connection from my LAN for employees, friends, family 
to use. I am thinking I can plug the second NIC into the router that 
outputs to my LAN and the other wifi routers and then point the VM to 
that NIC... is something like this possible. do I need to use the 
second NIC...  how do I go about this? Thanks
