Hi/Hola, >From some point of view, it is better to setup yourself a NTP server for the local LAN and allow NTP Server to update time to any ntp.*.com sources, then thru DHCP or manually configure users to update localtime from the loca resource, that way you can save a lot of traffic and efforts. Then open the UDP port 123 on your router and let's the traffic flow.
