Common Services

The following table lists some commonly-used services and their associated
protocols and port numbers. For a comprehensive list of port numbers, ICMP type/
code numbers and services, visit the IANA (Internet Assigned Number Authority)
web site.

Name: This is a short, descriptive name for the service. You can use this one or

create a different one, if you like.

Protocol: This is the type of IP protocol used by the service. If this is TCP/

UDP, then the service uses the same port number with TCP and UDP. If this is

USER-DEFINED, the Port(s) is the IP protocol number, not the port number.

Port(s): This value depends on the Protocol. Please refer to RFC 1700 for

further information about port numbers.

• If the Protocol is TCP, UDP, or TCP/UDP, this is the IP port number.
• If the Protocol is USER, this is the IP protocol number.

Description: This is a brief explanation of the applications that use this service

or the situations in which this service is used.
