Right I have got my self a device which requires internet sharing from my eth connection fir the past 2 weeks i was able to get it working but since removing avast it now worked straight away, why would avast block ics sharing.
I couldn’t find an option in Avast to stop that any help would be grateful?>
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.
Right so I reinstalled avast and disabled my ICS then disabled avast firewall and after setting up ICS again it worked so i restarted the firewall and its still ok.
