Hi gerardwil

When initiating outbound requests for common remote services (ie. HTTP for web browsing), your system will use ports some refer to as "ephemeral ports" or the "temp range" for the local portion of these connections. The ephemeral ports or temp range is 1024-5000. These would be the standard ports used locally for most connections to remote services. As you browse with each new outbound request to a web server (remote port 80), the port used on your system would change, gradually working it's way up through the ephemeral ports.

Thanks very much for explaining CrazyM.
