RUGGEDCOM ROX II
User Guide
• The daemon is configured manually with a list of peers to send to
• NTP servers issue advertisements to the daemon on broadcast or multicast address
NOTE
If a firewall is enabled, make sure UDP port 123 is open to send (if the router is an NTP client) or
receive (if the router is an NTP server).
NTP uses UDP/IP packets for data transfer, as UDP offers fast connections and response times, and transfers
them through UDP port 123.
