I am working with an old PC running Windows Vista on my home LAN.
I want it to be on my LAN for network sharing but don't want it to access the internet or have anything on the internet be able to access it.
I followed steps in this tutorial and created a Traffic Rule to block the mac address of the network card in the Vista PC.
Will this not only stop outgoing internet access from the PC but also incoming internet to that PC? I'm thinking of viruses etc..
