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.
Health Check Method: DNS Lookup
DNS lookups will be issued to test connectivity with target DNS servers. The connection will be treated as up if DNS
responses are received from one or both of the servers, regardless of whether the result was positive or negative.
Health Check
DNS Servers
This field allows you to specify two DNS hosts’ IP addresses with which con nectivity is to be
tested via DNS lookup.
If Use first two DNS servers as Health Check DNS Servers is checked, the first two DNS
servers will be the DNS lookup targets for checking a connection's health. If the box is not
checked, Host 1 must be filled, while a value for Host 2 is optional.
If Include public DNS servers is selected and no response is received from all specified
DNS servers, DNS lookups will also be issued to some public DNS servers. A WAN
connection will be treated as down only if there is also no response received from the public
DNS servers.
Connections will be considered as 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
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
