WAN Connection
Detection
Such function allows you to verify whether network
connection is alive or not through ARP Detect or Ping
Detect.
Mode – Choose ARP Detect, Ping Detect or Always On
for the system to execute for WAN detection. If you choose
Ping Detect as the detection mode, you have to type
required settings for the following items.
 Primary/Secondary Ping IP – If you choose Ping
Detect as detection mode, you have to type Primary or
Secondary IP address in this field for pinging.
 Ping Gateway IP – If you choose Ping Detect as
detection mode, you also can enable this setting to use
current WAN gateway IP address for pinging.
With the IP address(es) pinging, Vigor router can check
if the WAN connection is on or off.
 TTL (Time to Live) – Set TTL value of PING
operation.
 Ping Interval – Type the interval for the system to
execute the PING operation.
 Ping Retry – Type the number of times that the system
is allowed to execute the PING operation before WAN

packet passes through Vigor router, it will not be cancelled.
That is, the client who sends out the packet will not be
blocked by ISP.

for PPP.
Idle Timeout – Set the timeout for breaking down the
Internet after passing through the time without any action.

time you connect to it and request. In some case, your ISP
provides service to always assign you the same IP address
whenever you request. In this case, you can fill in this IP
address in the Fixed IP field. Please contact your ISP before
you want to use this function.
