NTP Server (default or
custom)
From the drop-down list, select an NTP server:
• Use Default NTP Servers. The VPN firewall’s RTC is updated regularly by
contacting a default NETGEAR NTP server on the Internet.
• Use Custom NTP Servers. The VPN firewall’s RTC is updated regularly
by contacting one of the two NTP servers (primary and backup), both of
which you must specify in the fields that become available with this menu
selection.
Note: If you select this option but leave either the Server 1 or Server 2 field
blank, both fields are set to the default NETGEAR NTP servers.
Note: A list of public NTP servers is available at
http://ntp.isc.org/bin/view/Servers/WebHome.
Server 1 Name / IP Address Enter the IP address or host name the primary
NTP server.
Server 2 Name / IP Address Enter the IP address or host name the backup
NTP server.
Note: If you select the default NTP servers or if you enter a custom server FQDN, the
VPN firewall determines the IP address of the NTP server by performing a DNS
lookup. You must configure a DNS server address on a WAN ISP Settings screen
(see “Manually Configuring the Internet Connection” on page 2-11) before the
VPN firewall can perform this lookup.
