Do I need a software firewall?

[Aidoscuz]

Hey all

I've been using Kerio Personal Firewall for the last while but after looking at some posts in this forum I've seen lots of people say that there's no need for a software firewall if you're behind a router. I've got a Netgear DG834G, so would the firewall on this be good enough to use on its own? Or would the router firewall backed up by the SP2 windows firewall be the best option?

Thanks

Thanks for the replies. I've uninstalled Kerio and stuck on the windows firewall, which has saved a nice bit of memory. Haven't been hacked so far
