Usage Guidelines
•
Use the no form of this command to disable UDP Relay for the specified service port.
•
Only use the port parameter to specify service port numbers that are not well known. For example, do
not specify port 53 as it is the well-known port number for DNS. Instead, use the DNS parameter to
enable relay for port 53.
•
The name parameter is only used with the port parameter and provides a user-defined description to
identify the not well-known port service.
•
When entering a name for a user-defined service, quotes are required around ambiguous characters,
such as hex characters, spaces, etc, so they are interpreted as text. For example, the name "A UDP
Protocol" requires quotes because of the spaces between the words.
