I have a machine with Windows 8.1 Pro and Norton Security 2015 installed. Hyper-V has been enabled and a VM with Windows 7 has been created. The VM has two virtual network adapters installed. One of those virtual adapters is configured to share a network connection with the host (Windows 8.1) machine.
When Norton's Smart Firewall is turned off on the (Windows 8.1) host machine, the Windows 7 VM is able to surf the internet. When the Smart Firewall is turned on, the VM is not able to access the internet.
How can I configure the Firewall on the host machine to allow the VM to access the internet?
