UDP ports above 1023 are allocated dynamically by certain services, so their exact port numbers may not be determined in advance.

Addresses can be listed as individual addresses (192.168.2.2) or IP address and CIDR netmask (192.168.2.0/24).

To easily configure UDP access for these ports, see “Opening the Firewall for Standard Services” on page 49. If you need more advanced firewall settings for these basic UDP services, use the following instructions to create them.
