I have been trying to learn VB the past hours, and until now I know very little about sockets and such.

I wondered if it was possible to close a specific socket for a IP and a specific port? (should be both protocols, but atleast UDP)

So basicly.. Be able to block a certain IP (and best of all would be if I could block this IP on a certain port aswell)

I know theres some tiny firewall app which probably could do this, but this doesnt support UDP.

Any Visual Basic Pro's which can help me out here?

Thanks alot!! good summer everyone!
