Virtual Pc Unable To Get Through Pc Bitdefender Firewall

Hi,


I have a number of different Microsoft Virtual PC 2007's, each running different operating systems & each one is having trouble accessing the internet through my physical PC Bitdefender Internet Secirity 2009 firewall...I have tried adding the virtualpc.exe via firewall advanced with no effect. If I switch of the physical PC firewall they all have access to the internet...please help!


Thanks Vince
