Multiple IPs, Virtual PC

All,

Has anyone tried to run Virtual PC on Windows 2003 Server in such a way that
you use multiple IP's on one NIC so that you can forward all traffic on
(say,) the second IP address to the Virtual PC?

For example:

Suppose the hardware NIC is set to x.y.z.100, and you add x.y.z.101 IP
address to that NIC; The Host OS (Win2k3 Server with DNS Component) uses
x.y.z.100, but adding a VM Guest running Win2k3 with the Web Services
(Application Server) Component.

Specifically, just for illustrative purposes, setting up a client side IPv4
so that DNS points to x.y.z.100, but when that client opens a browser and
points to http://x.y.z.101/ that the web running on the VC responds?



Is there a way to make all traffic to x.y.z.101 route to the VM/Web server?

If I understand you correctly, then yes... That's the way a guest VM works.
It shares the host's NIC, but has its own IP address assigned either
manually or through DHCP.

This happens to be rather common arrangement. Simply configure the Virtual
PC guest such that it uses the host's NIC as its network adapter - and
assign IP configuration either dynamically or statically...

The thing to remember is that the networking software does not know or
care whether a machine is a hardware box or a vm. You use exactly the same
network procedures. The NIC in the vm has its own MAC address and its own
IP address and looks just like any other machine on the network. You do not
need multiple IPs on the host NIC.

If I understand the question correctly, the OPs (Qazz) question is a little
more specific. I believe they are trying to see if they assign multiple IPs
to the Host, could they just get one IP to respond to guest activity. They
might be using the Guest as a NAT so they don't drain the IP pool of the
network. For example:

Host IPs
192.168.1.10
172.28.1.10

Guest IP (NAT Client)
192.168.2.20

Now Guest OS wants to access an external resource. How do you make sure
guest goes through 192.168.1.10 route rather than 172.28.1.10?
