This maybe a bit of a noob question, but do I need to turn on my firewall and if so what rules should should I add? I just bought a new router for Sky and can't remember if the Sky supplied one had firewall enabled or not. I also have an IPv6 hardware firewall in the router too but I think I am still using IPv4.
I have turned it on but as I have no rules in place I guess its the same as it being off?
It says this "Allow the packets not specified by any filtering rules to passthrough this device."
There's also a deny option but I'm guessing that would stop all traffic unless I specified what to let through.
I tried "Shields Up" website and everything was stealth, so no open ports or leaking information.
I used to use Zonealarm years ago, but now just use windows firewall too. I'm not sure how it works though because some things can connect to the internet even if they are not in the list. For example if I check for updates using VLC its connecting to the net, but its not in my windows firewall list at all. Maybe because its a user initiating the outgoing connection.
