16.4 Services Supported
The list box in the Rule Config(uration) screen (see Figure 16-4) displays all services that the Prestige
supports. Custom services may also be configured using the Custom Ports function discussed later. Next to
the name of the protocol, two fields appear in brackets. The first field indicates the IP port number that
defines the service (TCP Port, UDP Port, or ICMP Type). The second field indicates the IP protocol type (6
is TCP, 17 is UDP, or 1 is ICMP). 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. Click Custom Ports to configure new services.
