I just got broadband internet and would like to know something. I have 2 pcs hooked up. Does the firewall in the primary pc which the router in configured thru protect the second pc as well or does that one need its own firewall on. Also is the firewall active when the pc is powered off on both computers? The router came with the norton for a free trial but I already bought a new firewall for the primary pc so I want to know if that is okay to use. Thanks.
