13.10 Predefined Services
The Available Services list box in the Edit Rule screen (see Section 13.6.1 on page 151 )
displays all predefined services that the Prestige already supports. Next to the name of the
service, two fields appear in brackets. The first field indicates the IP protocol type (TCP, UDP,
or ICMP). The second field indicates the IP port number that defines the service. (Note that
there may be more than one IP protocol type. For example, look at the default configuration
labeled “(DNS)”.
(UDP/TCP:53) means UDP port 53 and TCP port 53. Up to 128 entries are
supported. Custom service ports may also be configured using the Edit Customized Services
function discussed previously.
