I think it depends on the networking. If your XP guest has bridged networking and gets its IP via DHCP from the host router, then you don't need to do anything special at the host. If your XP guest has NAT networking (Internal to Virtual PC and the guest), then it will have an IP range defined by Virtual PC. If that is what you are saying above, that x.x.131.x belongs to the XP guest, then on your host firewall, you need to permit the range x.x.131.0 - x.x.131.255. This will allow you to add more guests without changing your firewall. My terms bridged and NAT come from VMware, but these terms will have their countepart in Virtual PC and the concept is the same. ... Thinkpads_User

Well the host system has an IP adress that falls into the normal range of IP adresses 192.168.168.42 but the virtual machine is getting ip address 192.168.131.65. I tried to forward port 5905 to 192.168.131.65 because I am trying to run a vnc server on the remote system and it requires the LAN ip adress so it can resolver WAN requests for access to a certain port. For example I have a system on port 5904 and its IP is 192.168.168.139 I connect to it with my WAN IP address followed by the port that has been forwarded to the IP address http://xxx.xxx.xx.xxx:5904
My question is how can I forward the port from my enterprise firewall to the virtual system. Is it even possible? Could I do it with other software, can I use hyper-v server to do something like that?

I am an not certain about Virtual PC, but within VMware, I would use bridged networking so that the guest can get its IP from the outside world (192.168.168.x). I don't know if Virtual PC can do that, but with my VMware it is dead easy. Right now, your guest is getting a NAT'd IP address and that is not what you want.

All I can give you are workable concepts because I use VMware, and hopefully a Virtual PC expert will step in with more specifics. ... Thinkpads_User
