[quote name='whiteboy']alright, i already have a lynksis router does that mean a software firewall wont really do any good?[/quote]
A software firewall may still be a good idea, because, with Zone Alarm at least, you can restrict outgoing access to the internet on a program by program basis, I believe. So if you get infected with a virus or trojan or somesuch, you can cut it off before it can do much harm outside of your box.
