Blocking selected port , Can I do that?

Can I using Vb 5 to write a program,
which is running all the time to check some selected port, like FTP port

Can I blocking the port by using checkbox,
so that when I click the checkbox, the port have been blocked and no one can log in into my pc???

Can anyone help???

Your thinking of a firewall, that will block a specific port and deny any access to it.

The only other method you can do is to have the port open, as soon as a connection request comes in, log the attempt and close the port.

Problem is that this won't work when the port is already open, also i have never find something for vb anywhere to open/close/monitor connections like a program as @guard does.
