I finally got my NAT setup to work. I have 2 computers but only the one connected to the internet has a firewall setup. I am new to this. Do I need to add a firewall to my second computer? Or is it protected on every port by the first computers firewall.
You shouldn't need another firewall. The NAT function of the first system effectively hides the second system. If you level of paranoia is high enough, or you run wireless, a firewall on the second system wouldn't be a bad idea.
