I'm using a router for connecting my computer to a DSL Internet connection. The network is running fine, but I think that there are some ports blocked. Can anyone can help me configure my ports?

Well, blocking ports is a good thing. You only want to open ports for specific applications that need them. For example, to use Remote Desktop on a Windows XP machine you must forward port 3389 to the computer that will be the host. So, figure ut which applications are having problems and find out what port(s) they use. Then follow the instructions for your router in configuring the ports properly. Without more specific information, I don't know that anyone can provide much more. If you were to list the applications you are having problems with, someone could indicate what ports need to be forwarded. And if you were to provide your router make/model someone could provide instructions on configuring the ports in the router. Short of that we would have to use the crystal ball. Michael J

Just to give an idea of the scale of the problem outlined by Michael, there are over 65,000 ports available on the Internet. Stuart

You could put your computer in a DMZ on your router if you wanted to get around this, but the previous post was right. You DON'T want all ports open unless you absolutely have to. The ports are closed for your protection. "...but in my defense, it was dark, I was drunk, and it was delicious!"
