WAN Health Check
To ensure traffic is routed to healthy WAN connections only, the Pepwave router can periodically
check the health of each WAN connection. The health check settings for each WAN connection
can be independently configured via
Network>WAN>Details
.
Health Check Settings
Method
This setting specifies the health check method for the WAN connection. This value
can be configured as
Disabled
,
PING
,
DNS Lookup
, or
HTTP
. The default method
is
DNS Lookup
. For mobile Internet connections, the value of
Method
can be
configured as
Disabled
or
SmartCheck
.
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.
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.
