Use the SNTP Source Interface Configuration page to specify the physical or logical interface to use as the SNTP (Simple Network Time Protocol) client source interface. When an IP address is configured on the source interface, this address is used for all SNTP communications between the local SNTP client and the remote SNTP server. The IP address of the designated source interface is used in the IP header of SNTP management protocol packets. This allows security devices, such as firewalls, to identify all source packets coming from a specific device.
