5.3.4.7.5 Addition of Exceptions to Standard Restrictions
After the standard restrictions have been set once, certain exceptions may be necessary for
special hosts/sub-networks in order to allow remote time servers and client hosts/sub-
networks to contact the NTP service.
These standard restrictions are to be added in the form of restriction lines.
An unrestricted access of the Time Client 8029NTC to its own NTP service
is always allowed, irrespective of whether standard restrictions are ignored
or not. This is necessary in order to be able to display NTP data on the
web interface.
