Automatic Public DNS Server Check on DNS Test Failure
When the health check method is set to DNS Lookup and health checks fail, the Pepwave router will
automatically perform DNS lookups on public DNS servers. If the tests are successful, the WAN may not
be down, but rather the target DNS server malfunctioned. You will see the following warning message on
the main page:

Dynamic DNS Settings

9.5
Pepwave routers are capable of registering the domain name relationships to dynamic 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 router),
the public IP of each WAN will be automatically reported to the DNS service provider.
Either upon a change in IP addresses or every 23 days without link reconnection, the Pepwave
router will connect to the dynamic DNS service provider to perform an IP address update within
the provider's records.

Other Health Check Settings
This setting specifies the timeout in seconds for ping/DNS lookup requests. The
default timeout is 5 seconds.
This setting specifies the time interval in seconds between ping or DNS lookup
requests. The default health check interval is 5 seconds.
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.
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.
