The port number that is the lower in a specified range.
You specify the higher port number with the -maxport parameter. Ports below 1025 are usually reserved for system TCP and UDP. The range of port numbers defined by the -maxport and -minport parameters provides client access to an OpenEdge server that is behind a firewall. This communication is possible only when the access to the server can be limited.
