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
