Reverse Proxy 2007 and 2010 CAS - TMG 2010

Current Setup (Not a production environment - Lab setup for EXO Hybrid Configuration):

1 public ip

dmz set to NIC 2 on TMG

NIC 1 : 192.168.1.103 (Through DHCP server)

NIC 2: 192.168.1.105 (Manual Assignment)

Gateway: 192.168.1.1

Intended setup:

Requests for https://mail.domain.com from the internet -> TMG -> Internal 2007 CAS IP

Requests for https://hybrid.domain.com from the internet -> TMG -> Internal 2010 CAS IP 192.168.1.103 (TMG is installed on 2010 CAS)

Requests for https://fs.domain.com from the internet -> TMG -> Internal FS IP

Is this even possible to achieve through TMG 2010?

Thanks!
