https://community.hpe.com/t5/operating-system-hp-ux/print-protocol-return-port-assignment/m-p/2511774#M595757 Hello, <BR /><BR />Would anyone be able to validate the printer protocol return port assignment? <BR /><BR />We are trying to configure a router to allow the printer port 515, in doing <BR />so we need to understand what the return port range will be? <BR /><BR />Initial tests seem to indicate it uses ports less than 1023, however it's <BR />unclear what ports are being utilized. <BR /><BR />Below are some netstat entries from some failed connections. <BR />These results tend to support &gt; 1020, however if anyone could validate <BR />it would be really appreciated. This is based on hpsh01 initiating the <BR />connections. <BR /><BR />hpsh01: /home/rvanclea $&gt; netstat -an | grep 515 <BR />tcp 0 1 156.153.110.1.1022 15.19.50.73.515 SYN_SENT <BR />tcp 0 1 156.153.110.1.1021 15.19.50.73.515 SYN_SENT <BR />tcp 0 1 156.153.110.1.1020 15.19.50.73.515 SYN_SENT <BR />tcp 0 0 *.515 *.* LISTEN <BR /><BR /><BR />m2496cxb: /home/ronvc $&gt; netstat -an | grep 515 <BR />tcp 0 0 *.515 *.* LISTEN <BR />tcp 0 2 15.19.50.73.515 156.153.110.1.1022 FIN_WAIT_1 <BR />tcp 0 2 15.19.50.73.515 156.153.110.1.1021 FIN_WAIT_1 <BR />tcp 0 2 15.19.50.73.515 156.153.110.1.1020 FIN_WAIT_1 <BR /><BR /><BR />Ron.
