6.5 WAN Technical Reference

This section provides some technical background information about the topics
covered in this chapter.

6.5.1 Encapsulation

Be sure to use the encapsulation method required by your ISP. The ZyXEL Device
supports the following methods.
P-2612HW-F1 User's Guide
DESCRIPTION
When the ZyXEL Device is using a lower priority connection (usually a
WAN backup connection), it periodically checks whether or not it can use
a higher priority connection.
Type the number of seconds (30 recommended) for the ZyXEL Device to
wait between checks. Allow more time if your destination IP address
handles lots of traffic.
Type the number of seconds (3 recommended) for your ZyXEL Device to
wait for a ping response from one of the IP addresses in the Check
WAN IP Address field before timing out the request. The WAN
connection is considered "down" after the ZyXEL Device times out the
number of times specified in the Fail Tolerance field. Use a higher
value in this field if your network is busy or congested.
Traffic redirect forwards traffic to a backup gateway when the ZyXEL
Device cannot connect to the Internet.
Select this check box to have the ZyXEL Device use traffic redirect if the
normal WAN connection goes down.
Note: If you activate traffic redirect, you must configure at least one
Check WAN IP Address.
This field sets this route's priority among the routes the ZyXEL Device
uses.
The metric represents the "cost of transmission". A router determines
the best route for transmission by choosing a path with the lowest
"cost". RIP routing uses hop count as the measurement of cost, with a
minimum of "1" for directly connected networks. The number must be
between "1" and "15"; a number greater than "15" means the link is
down. The smaller the number, the lower the "cost".
Type the IP address of your backup gateway in dotted decimal notation.
The ZyXEL Device automatically forwards traffic to this IP address if the
ZyXEL Device's Internet connection terminates.
