Well I guess there might be different ways, but how about firewall? Or some security programs like hacker protect etc..

cheers

I should have been more specific. I have an excelent firewall, but there is still one port that needs to be blocked, and I don't know how to block it manually. There may be more, but if I can learn how to close one, I can probably block any others that are open. Only one leaked when I ran the test.
Thanx

Depends on your firewall and/or your OS as to how to block the port.

What firewall are you running?

A real firewall should start out blocking everything, and you then open the ports you want to use. My home router uses NAT to shield the network from direct queries to PCs, and by default blocks all ports (incoming). If I want a particular port to be forwarded directly to a particular PC on the network, I can specify that in the router set up.

There are also software port blockers that you can download, though in my experience, they were not very intuitive.

My router wouldn't work correctly, so after about 90 hours of effort to try and get it set up, we just gave up on it. I don't know what you mean by "a real firewall". When I first installed SPF it did block everything. But somehow at least one of the ports is not blocked, and I just want to learn how to block specific ports.

ZoneAlarm Pro can have a conflict with COX Cable, I was told by a COX technician. It also costs money and I have no income, so I'll just have to continue with SPF.
Thanx
