11.11.2 Predefined Services

The Predefined Services table in the Service screen displays all predefined services that the
ZyWALL 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, DNS (UDP/TCP:53) means UDP port 53 and TCP port 53.
