DESCRIPTION
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.
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.
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).
