Health Check Disabled
When ​ Disabled ​ is chosen in the ​ Method ​ field, the WAN connection will always be considered as up. The
connection will ​ NOT ​ be treated as down in the event of IP routing errors.
Health Check Method: PING
ICMP ping packets will be issued to test the connectivity with a configurable target IP address or hostname. A WAN
connection is considered as up if ping responses are received from either one or both of the ping hosts.
PING Hosts
This setting specifies IP addresses or hostnames with which connectivity is to be tested
via ICMP ping. If
​ Use first two DNS servers as Ping Hosts ​ is checked, the target ping
host will be the first DNS server for the corresponding WAN connection. Reliable ping
hosts with a high uptime should be considered. By default, the first two DNS servers of
the WAN connection are used as the ping hosts.
