unless your running a firewall or using a router, by default all 65,000 ports are open and listening. Need to know how you are physically connecting to the internet. What hardware your using to do so. What firewall , if any, your using, and what program needs TCP port 6801 and UDP port 6801 and 6801? you can check open port status on W2K by using the netstat utility from a command prompt.

Normally, a software program what requires internet access on a specific port will bind to the ports it needs and only specifies an error on connection if the ports have been closed by either software or hardware protection [As mentioned above] or another program is already using the ports.

What is doing the connection sharing? Windows 2000 or a DSL/Cable router?

Either way, I suspect your problem is with NAT (network address translation).

If you are using a DSL/Cable router, you will need to enable it's "virtual server" or port mapping features. You will need to refer to your documentation. In short, this will "open" the port and listen for incoming traffic. Then when traffic is heard on a specific port, it will pass that traffic to a specific computer on the internal network.

If you are using win2k for connection sharing, it has no firewall capabilties, and is therefore already listening on every port. However, you still need to tell it to pass traffic on a specific port to another computer on the internal network.

Go to the internet connection properties, select the sharing tab, then click the settings button. Select the services tab, then add a service for your specific application.

These ports need to be opened for an IP Telephony application to make VoIP calls. W2k is doing the internet sharing. NAT is the problem. I am not using a proxy, firewall or router.

Do a search for a file called services in windows 9x it is in the windows directory this file has a list of ports add your ports there and things should work you may have to search for the services file on the win2k machine also, I believe that it is in the system32/drivers/etc folder but I am not postive of that. You will need to know the app name that requires these ports as you will see when you edit the services file.

I wasable to solve the problem with Win2k with the "services" in the "internet connection". It does not exist with Win98.
