If I try to connect to a server which is not listening on a port, my connection fails immediately with "the target machine actively refused the connection" (because its remote IP stack received the request but refused the connection because the port is not open).
The behavior of a firewall is to make it look exactly like a server is not listening on a port. So with a firewall you receive "the target machine actively refused the connection" and it looks no different than a server without that open port.

Actively refused means nobody is listening on that port. Adam.. -----Original Message----- From: Discussion of advanced .NET topics.

Interesting.
