Figure 50 WAN Backup Setup Chapter 5 WAN Setup The following table describes the labels in this screen. Table 26 WAN Backup Setup LABEL DESCRIPTION Backup Type Select the method that the ZyXEL Device uses to check the DSL connection. Select DSL Link to have the ZyXEL Device check if the connection to the DSLAM is up. Select ICMP to have the ZyXEL Device periodically ping the IP addresses configured in the Check WAN IP Address fields. Check WAN IP Address1-3 Configure this field to test your ZyXEL Device's WAN accessibility. Type the IP address of a reliable nearby computer (for example, your ISP's DNS server address). Note: If you activate either traffic redirect or dial backup, you must configure at least one IP address here. When using a WAN backup connection, the ZyXEL Device periodically pings the addresses configured here and uses the other WAN backup connection (if configured) if there is no response. Fail Tolerance Type the number of times (2 recommended) that your ZyXEL Device may ping the IP addresses configured in the Check WAN IP Address field without getting a response before switching to a WAN backup connection (or a different WAN backup connection). Recovery Interval When the ZyXEL Device is using a lower priority connection (usually a WAN backup connection), it periodically checks to 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. P-662H/HW-D Series User's Guide 95
