Other Health Check Settings
Timeout
This setting specifies the timeout in seconds for ping/DNS lookup requests. The default
timeout is 5 seconds.
Health Check
Interval
This setting specifies the time interval in seconds between ping or DNS lookup requests.
The default health check interval is 5 seconds.
Health Check
Retries
This setting specifies the number of consecutive ping/DNS lookup timeouts after which the
Pepwave router will treat the corresponding WAN connection as down. Default health
retries is set to 3. Using the default Health Retries setting of 3, the corresponding WAN
connection will be treated as down after three consecutive timeouts.
Recovery
Retries
This setting specifies the number of consecutive successful ping/DNS lookup responses
that must be received before the Pepwave router treats a previously down WAN connection
as up again. By default, Recover Retries is set to 3. Using the default setting, a WAN
connection that is treated as down will be considered as up again upon receiving three
consecutive successful ping/DNS lookup responses.

target DNS server malfunctioned. You will see the following warning message on the main page:

DNS service providers. Through registration with dynamic DNS service provider(s), the
default public Internet IP address of each WAN connection can be associated with a
host name. With dynamic DNS service enabled for a WAN connection, you can connect
to your WAN's IP address from the external, even if its IP address is dynamic. You must
register for an account from the listed dynamic DNS service providers before enabling
this option.
If the WAN connection's IP address is a reserved private IP address (i.e., behind a NAT
