Wait i'm hearing different things from different people. So should the modem firewall be set on high or off or just left on basic? I'm sure NAT is on.
Zone Alarm is set on High for Internet, Medium for Trusted and low for programs because he doesn't want to be bothered with pop ups for every program wanting to access the internet. Which is fine unless a spyware program is on his pc. But he runs spyware scans often and like I said in another forum for networking I entered his friends pc ip address and named it so and so computer and set it on trusted and did the same for the other pc.
According to this site:

Step 6:
On this page we can setup the routers firewall. There is four choices we can set.
The first is High which offers the most protection. It will block all traffic to your network.
The next is Medium we assume this offers slightly less protection than High.
The third is Low we assume this offers less protection than Medium.
Last we have Basic offers NATing and no firewalling.
