LABEL DESCRIPTION
Active/Passive
(Fail Over) Mode
The ZyXEL Device uses the second highest priority WAN interface as a back up.
This means that the ZyXEL Device will normally use the highest priority (primary)
WAN interface (depending on the priorities you configure in the Route Priority
fields). The ZyXEL Device will switch to the secondary (second highest priority)
WAN interface when the primary WAN interface's connection fails.
Fall Back to
Primary WAN
When Possible
This field determines the action the ZyXEL Device takes after the primary WAN
interface fails and the ZyXEL Device starts using the secondary WAN interface.
Select this check box to have the ZyXEL Device change back to using the primary
WAN interface when the ZyXEL Device can connect through the primary WAN
interface again.
Clear this check box to have the ZyXEL Device continue using the secondary WAN
interface, even after the ZyXEL Device can connect through the primary WAN
interface again. The ZyXEL Device continues to use the secondary WAN interface
until it's connection fails (at which time it will change back to using the primary
WAN interface if its connection is up.
Route Priority
WAN1
WAN2
Traffic Redirect The default WAN connection is “1” as your broadband connection via the WAN
interface should always be your preferred method of accessing the WAN. The
ZyXEL Device switches from WAN interface 1 to WAN interface 2 if WAN interface
1's connection fails and then back to WAN interface 1 when WAN interface 1's
connection comes back up. The default priority of the routes is WAN 1, WAN 2 and
then Traffic Redirect:
You have two choices for an auxiliary connection (WAN 2 and Traffic Redirect) in
the event that your regular WAN connection goes down.
Connectivity
Check
Check Period The ZyXEL Device tests a WAN connection by periodically sending a ping to either
the default gateway or the address in the Ping this Address field.
Type a number of seconds (5 to 300) to set the time interval between checks. Allow
more time if your destination IP address handles lots of traffic.
Check Timeout Type the number of seconds (1 to 10) for your ZyXEL Device to wait for a response
to the ping before considering the check to have failed. This setting must be less
than the Check Period. Use a higher value in this field if your network is busy or
congested.
Check Fail
Tolerance
Type how many WAN connection checks can fail (1-10) before the connection is
considered "down" (not connected). The ZyXEL Device still checks a "down"
connection to detect if it reconnects.
Check WAN1/2
Connectivity
Select the check box to have the ZyXEL Device periodically test the respective
WAN interface's connection.
Select Ping Default Gateway to have the ZyXEL Device ping the WAN interface's
default gateway IP address.
Select Ping this Address and enter a domain name or IP address of a reliable
nearby computer (for example, your ISP's DNS server address) to have the ZyXEL
Device ping that address. For a domain name, use up to 63 alphanumeric
characters (hyphens, periods and the underscore are also allowed) without
spaces.
