my Windows Firewall blocks internet access for connected devices via Internet Connection Sharing (ICS).


On my Windows 10 Pro (1607) machine (HP ProBook 450 G4), I want to share my wired Ethernet internet connection via WiFi. I want to use this connection with my HTC One m7 device. When I activate a mobile hotspot under Settings > Network & Internet > Mobile hotspot all looks fine. I connect my phone to this new WiFi and open chrome browser. When I try to open a website I see an error: ERR_NAME_NOT_RESOLVED.

When I deactivate Windows Firewall for public networks it works fine, connections to internet server can be established.

When I check Network and Sharing Center, I see two active networks: One private one with two connections (Ethernet and WiFi) and one public one with one connection ("LAN connection* 13").


So actually, I get it to work, but I don't want to leave my firewall deactivated, especially for public networks. Does anyone know which rule I have to add to my firewall settings to permanently allow all traffic passing through from and to "LAN connection* 13"? (Just to be clear, I don't need port forwarding through Window's NAT, I just want to allow devices in the shared connection to use internet.)
