If the device server is configured to use DHCP, it will try to get
NTP server information from the DHCP server. You may also
manually set up the addresses on this page. The NTP service
uses UDP port 123. If your device server is behind a firewall
you may need to allow accesses to this port through the
firewall. Adding or changing the NTP server will trigger the
Host RJ‐11 IP Gateway to get the time again.
The HTTP server you specify need not be a designated time
server – just a reliable server. The device server derives the
system time from the HTTP header the server returns. Adding
an HTTP server will not automatically trigger getting the time.
You must reboot for this to take effect.
