Terminal Server with 2 NICs

Looking hi and low for some sort of info but no luck. Here is the scenario.
Terminal Server
enable NIC 192.168.100.14
Second NIC (we want to use .13)
reason:
CFS Filtering thru Sonicwall is IP based.
So I want CEO’s to use .14 so they are not effect
All other users to use .13 so they can’t user restricted sites
Tried adding RDP in Terminal Services configuration and binded RDP session to proper NIC card
But once I do that can’t use any RDP session and need to revert back.
There needs to be step by step tutorial to get this done. Just can’t seem to properly search…
