Linux has a firewall more or less built right into it. It is usually configured with the command ipfwadm. Look in /usr/doc/howto/ or similar for the ipfwadm howto file, which gives you a quick look at both simple and more advanced ways of firewalling both the Linux computer, or using it as a masquerading NAT firewall for your entire network.
But, as Someone(TM) says, your router likely has some firewall capability, if it's not a modular 'single task' router, made for the addition of a hardware firewall in addition to the router.
