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.
