NTP Service
A NTP Server allows the PCs, servers and other network devices to synchronize their time
with the same reference: the NAS. It is useful (and sometimes required) to keep the time
synchronized for all devices in some environments.
Setting up NTP Server
To set up the NTP Server, first go to "Control Panel" > "Applications" > "NTP Service" and
check "Enable NTP Server". Select to check the following three operating modes:
 Broadcast: This will allow the NTP server to periodically send broadcast packets with the
IP address "255.255.255.255 ". Clients compatible with this mode can use this to
synchronize their time.
 Multicast: This will allow the NTP server to periodically send multicast packets. Clients
compatible with this mode can use this to synchronize their time. Specify the multicast IP
address after this option is enabled.
 Manycast: This will allow the NTP server to listen for manycast requests from NTP clients
and reply to the client requests received. Specify the manycast address after this option
is enabled.
Note: For multicast and manycast modes, the NTP clients will only receive this kind of
packets after they are configured for the modes. Please refer to their user manuals for
setup details.
