2 NICs One PC - Homebuilt NOC monitoring 2 seperate networks

[w4nn4b1337]

I have a challenge I am researching and I wanted to throw this out there to even see if it was possible. I manage a small campus network but in the small campus are 2 seperate autonomous networks. I can not join them together but I do need to monitor both.
I have patched both circuits to my homebuilt NOC monioring server. It does have 2 GIG NIC's and the system is running WIndows 7.
I don't think it is possible to have 2 seperate gateway's on this system and that is not what I am trying to accomplish.
What I am trying to do is Use NIC 1 to have the host operating system use Network A and then use NIC 2 to map strictly to a VMWARE Workstation virtualized Windows7 system to monitor Network B.
However, the Gateway problem persists. I can not get NIC 1 to use Network "A" and NIC 2 to map only to the VMWARE host. It is one or the other. Is it possible to monitor 2 autonomous networks with one system this way? Your thoughts and comments are appreciated.

have you attempted to set the VMNIC setting to BRIDGED and told it to use NIC2...

Virtual Network settings can be found under EDIT, on VMWare Workstation...

Yes I did - unfortunatly though everything else decided to use that NIC as well. So it worked but I lost connection to Network A.
I did find the solution though.
It is to disable all protocols except for VMWARE protocols. Bridge the physical NIC 2 to the VMNIC so the VM gets the DHCP address instead of the physical network stack.
NIC1 stays on Network A and NIC2 can not bind to TCP/IP or anything else but the bridged VMNIC. Once the VM is powered up, it sees the bridged NIC and passes the DHCP assignment from Network B. WOrking like a charm

glad you found the solution and thank you for posting how you achieved that...
