4.16.3 NTP
The NTP configuration form allows you to configure the NTP client. To open the NTP page,
click NTP in the Configuration section of the main menu. NTP (Network Time Protocol) allows
you to periodically set the internal clock of the router. The time is set from servers that provide
the exact time to network devices. IPv6 Time Servers are supported.
• If you mark the Enable local NTP service check box, then the router acts as a NTP server
for other devices in the local network (LAN).
• If you mark the Synchronize clock with NTP server check box, then the router acts as a
NTP client. This means that the router automatically adjusts the internal clock every 24
hours.
