One RRAS VM and 3 subnets...is it possible?

All,

I'll be setting up a lab to simulate a standard network where there will would be two firewalled networks, so essentially;

Internet <==> DMZ <==> Internal Network

I know that with RRAS, I can route between two different subnets, though was curious if with just one RRAS VM, could I interconnect the three networks for the sake of testing?

If not, then I know I have to have 2 RRAS VMs interconnecting the networks I simply laid out.

Thanks,

Christian
