The client then tries to connect to the server using Tcp1.Connect("xxx.xxx.xxx.xxx", "7") When a connection is made I display the connection's RemoteEndPoint and it gives me the correct IP address (of the client) but the port number isn't 7. Also, when I repeatedly connect and disconnect the client from the server the port number the server displays seems to increment upwards. I'm totally confused. Where is it getting this other port?

When someone connects, a new port is created (we request it from the TCP-IP stack), the connection is then "handed over" to the new port and the server goes back to listening.
