two DNS servers of the WAN connection are used as the health check DNS servers.
Health Check Method: HTTP
HTTP connections will be issued to test connectivity with configurable URLs and strings to match.
URL1
WAN Settings>WAN Edit>Health Check Settings>URL1
The URL will be retrieved when performing an HTTP health check. When ​ String to Match
is left blank, a health check will pass if the HTTP return code is between 200 and 299
(Note: HTTP redirection codes 301 or 302 are treated as failures). When
​ String to Match ​ is
filled, a health check will pass if the HTTP return code is between 200 and 299 and if the
HTTP response content contains the string.
URL 2

If ​ URL2 ​ is also provided, a health check will pass if either one of the tests passed.
