Windows + Share internet connection no connection to new machine

[zgzg2020]

Hi,
My setup is as follows:
ComputerA has two ethernet plugs 1 and 2.
ComputerA.plug1 is connect to the internet.
ComputerA.plug2 is connect to the computerB.
ComputerA.plug1.Properties.Sharing.InternetConnectionSharing(check)->HomeNetworkingConnection(ComputerA.plug2)

When simplewall filters are disabled:
ComputerB can connect to the internet.

When simplewall filters are enabled:
ComputerB can NOT connect to the internet.

I am new with ports/firewall rules...etc. But, I tried adding every rule I could, yet could not make it work.

Please help!

This shows up in the "Packet Log", I try to add it as a rule, yet doesn't work, even without a port.

Anybody has any ideas???

There's probably additional services that require whitelisting.
What if you just whitelist svchost in the apps pane.

have you enabled "SharedAccess" in the services tab? that allows internet connection to virtual network adapters. any exectable or computer that uses virtual network adapter will have full internet access with that service enabled.

Yes, it is enabled.
