Check WAN IP Address1-3 Select DSL Link to have the P-792H v2 check if the connection to the DSLAM is up. Select ICMP to have the P-792H v2 periodically ping the IP addresses configured in the Check WAN IP Address fields. Configure this field to test your P-792H v2's WAN accessibility. Type the IP address of a reliable nearby computer (for example, your ISP's DNS server address). If you activate either traffic redirect or dial backup, you must configure at least one IP address here. Fail Tolerance When using a WAN backup connection, the P-792H v2 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 P-792H v2 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).
