Is your firewall network profile in private or puplic mode?

=================================================================

NOTE:The Network profiles control the settings which determine how strictly Firewall protects your PC.

Private: a lower level of security suitable for when your PC is connected to a trusted network such as your home or work network.
This profile enables better connectivity, and permits all communication within the network.

Public: a higher level of security suitable for when your PC is connected to a public network such as in a cafe or airport.
Because public networks present greater security risks, no incoming communication is permitted when this profile is set.
