With most routers, if you haven't configured it, the NAT firewall should be on by default.

However, a software firewall behind the hardware one is a very good idea; particularly since most router firewalls only check incoming traffic. A good software firewall such as Zone Alarm also checks outgoing traffic - this can be very useful sometimes.

But, as Aragorn points out, you may need to configure the software firewalls to allow the other machines on your network: Aragorn suggested doing this by computer name, but you can also do it by IP number.
