I'm looking for a firewall which is light. And yet, requires little user intervention. Cuz I'm planning to install this firewall on my parents' PC as they have no idea whether to allow or disallow traffic. So, I'm looking at a firewall which can run on its own and basically don't even require any user intervention. Honestly, I have no idea whether to allow or disallow certain traffic at times too. Cuz I'm not technically-savvy. So, my knowledge on tweaking and configuration is very limited too. Does GhostWall Firewall requires much user intervention? Is it suitable to be installed on my parents' computers?
