Using the POOL option to set a range of port numbers

After the port allocation algorithm assigns a well-known port to each process, all subsequent ports allocated for connections between components are opaque ports; that is, any available port can be allocated for a connection. You can limit opaque port allocations to a specific range of ports by coding the POOL option with any protocol specified on the KDE_TRANSPORT environment variable.

The POOL option must specify a range of ports no smaller than 2 and no larger than 1024. POOL:1000-2023 is valid; POOL:1000-2024 is not. If more than 1024 ports are required in a pool for a specific protocol, you can code more than one POOL option, as in POOL:1000-2023 POOL:3000-4023.
