• Use Default NTP Servers : If this is enabled, then the RTC (Real-Time Clock) is updated
regularly by contacting a Default Netgear NTP Server on the Internet.
• Use Custom NTP Servers : If you prefer to use a particular NTP server, enable this
instead and enter the name or IP address of an NTP Server in the Server 1 Name/IP
Address field.
If required, you can also enter the address of another NTP server in the Server 2 Name/IP
Address field. If you select this option and leave either the Server 1 or Server 2 fields
empty, they will be set to the Default Netgear NTP servers.

Monitoring the Router
You can be alerted to important events such as WAN port rollover, WAN traffic limits reached, and
login failures and attacks. You can also view status information about the firewall, WAN ports, and
LAN ports, and program SNMP connections.
Enabling the Traffic Meter
To monitor traffic limits on each of the WAN ports, select Administration from the main menu
and Traffic Meter from the submenu. The Wan1 Traffic Meter screen will display. (The WAN1
WAN2, WAN3 and WAN4 ports are programmed separately.) A WAN port shuts down once its
traffic limit is reached if the
Block all traffic feature is enabled.
