Dns Address Configuration; Check Connection To Mobile Network Configuration - Advantech B+B SmartWorx LR77 v2 Configuration Manual

Parameters identified with an asterisk require you to enter the appropriate information only
if this information is required by the mobile network carrier.
When the router is unsuccessful in establishing a connection to mobile network, verify
accuracy of the entered data. Alternatively, you can try a different authentication method or
network type.
3.3.2 DNS Address Configuration
The DNS Settings parameter is designed for easier configuration on the client side. When
you set the value to get from opertor the router attempts to automatically obtain an IP address
from the primary and secondary DNS server of the mobile network carrier. To specify the IP
addresses of the Primary DNS servers manually, from the DNS Server pull down list, select
the value set manually.
3.3.3 Check Connection to Mobile Network Configuration
If the Check Connection item is set to enabled or enabled + bind, it activates checking
the connection to the mobile network. The router will automatically send ping requests to the
specified domain or IP address (Ping IP Address item) at regular time intervals (Ping Interval).
In case of unsuccessful ping, a new one will be sent after ten seconds. If it fails to ping the IP
address three times in a row, the router terminates the current connection and tries to establish
new ones. Checking can be set separately for two SIM cards or two APNs. Send an ICMP to
an IP address that you know is still functional. (The operator's DNS server, for example.)
If the Check Connection item is set to the enabled option, ping requests are sent on the
basis of routing table. Thus, the requests may be sent through any available interface. If you
require each ping request to be sent through the network interface, which was created when
establishing a connection to the mobile operator, it is necessary to set the Check Connection
item to enabled + bind. The disabled option deactivates checking the connection to the mobile
network.

Table 20: Check Connection to Mobile Network Configuration
If you mark the Enable Traffic Monitoring checkbox, then the router stops sending ping
request to the Ping IP Address and it monitors the data stream on the connection to mobile
network. If this connection is without data longer than the Ping Interval, then the router sends
a ping request to the Ping IP Address.
Enabling the Check Connection function for mobile networks is necessary for uninter-
rupted and lasting operation of the router.

queries.
Specifies the time intervals between the outgoing pings.
