That's basically my whole project.
Using hyper-V.
RRAS has 3 NICs.
1st NIC connected to the 1st subnet.
2nd NIC to the 2nd subnet.
3rd nic connected to TMG.
What i wanted to do is divide my whole network into internal and external.
so the 192.168.3 subnet is the internal network.
Whereas the undefined NIC going out of the TMG connected to my router is the external.
All NICs in my network are set as internal, except for the one connected to my router which is External and using the Local Area adapter of the laptop.
What's the basic configuration i should do on the external network card, and in TMG ?
Cheers mate
