There are quite a few problems with running a config like that. The
simplest solution is to run RRAS in a vm rather than on the host. Put the
vms on a private virtual network (no connection to the host) and run a vm as
a RRAS router (I run W2k3 with RRAS using 512M of memory). This gets around
the problems caused by Server 2008 assigning network profiles to the
networks which you don't really want. Otherwise you need to fiddle with the
advanced firewall settings to make it do what you want.

You can use a 2008 vm as your router if you like. (Or Linux for that
matter). I use 2003 because it does the job and runs happily.

How does your host connect to the physical network? If it is on a network
which uses DHCP the RRAS server can get its network config the same way that
the host gets its config. My Hyper-V host is on a LAN behind a D-Link
router.

Why should the RRAS server's MAC address not appear on the LAN? What
problems would it cause? (Having the 2008 server register two interfaces
with two MAC addresses (as you do now) is a problem.) If you don't want the
LAN machines to see the RRAS server, disable Netbios over TCP/IP and set it
to not register in DNS.

Isolate your LAN from the ISP by putting a router in between (D-link
for example). Then let the router be the DHCP server on your LAN. Now
you can have as many MAC addresses as you like on your network, the
only one seen by the ISP is the router's MAC address.
