+If your system runs a firewall, ensure that ports 319 and 320 are open for UDP traffic in both directions. These ports are associated with PTP service and may be referred to as "PTP" in firewall rules. For example, the following would open ports 319 and 320 for Fedora, which uses `firewalld`:

+# firewall-cmd --permanent --add-service=ptp

 ## Notes
 Please note that `nqptp` must run in `root` mode to be able to access ports 319 and 320.
