3.7.1. SNTP
Time synchronization is an essential element for any business, which relies on the IT system. The reason for this is that
these systems all have clock that is the source of timer for their filing or operations. Without time synchronization,
these system’s clocks vary and cause the failure of firewall packet filtering schedule processes, compromised security,
or virtual server working in wrong schedule.
SNTP is the acronym for Simple Network T ime Protocol, which is an adaptation of the Network Time Protocol (NTP)
used to synchronize computer clocks in the Internet. SNTP can be used when the ultimate performance of the full NTP
implementation. The function only supported on router mode.
There are two methods to synchronize time, synchronize with PC or SNTP. If you choose synchron ize with PC, the VPN
Router will synchronize with PC ’s internal timer. If you choose SNTP, the VPN Router will use the protocol to
synchronize with the time server. For synchronization the time server with SNTP, needs to configure service,
time_server and time_zone. For synchronization with PC, doesn’t need to configure the above parameters.
