[REBOL] Re: Opening Specific Ports

From: antonr:iinet:au at: 13-Nov-2003 13:17

Yes, in this case you have *two* connections, and so, four ports. But you only care about the server-side port numbers. In FTP, the ftp server acts first as a server, but when a client requests information, the server connects back to the client as a "client". Other programs like peer-to-peer file-sharing programs also have two sets of ports in the specifications. That's because they also make connections as a client and as a server. You might see written in the settings: "client ports xxx - yyy". That actually means "clients connect to me on my ports xxx - yyy". It isn't the client-side port number at all being referred to.
