WAN connection will be treated as down only if there is also no response received from the
public DNS servers.
Connections will be considered up if DNS responses are received from any one of the
health check DNS servers, regardless of a positive or negative result.
By default, the first two DNS servers of the WAN connection are used as the Health Check
DNS Servers.
Health Check Method: HTTP
URL 1
HTTP connections will be issued to test the connectivity with configurable URLs and strings
to match.
WAN Settings > WAN Edit > Health Check Settings > URL 1
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
WAN Settings > WAN Edit > Health Check Settings > URL 2
If URL 2 is also provided, a health check will pass if either one of the tests passed
.
