Doc Type:	Bug Fix
Doc Text:	The ntpd daemon dropped incoming NTP packets if their source port was lower than 123 (the NTP port). As a consequence, clients behind Network Address Translation (NAT) were unable to synchronize with the server if their source port was translated to ports below 123. With this update, ntpd no longer checks the source port number, and clients behind NAT are now able to correctly synchronize with the server.
