4.3 Mobile WAN Configuration
4.3.3 Check Connection to Mobile Network Configuration
Enabling the
Check Connection
function for mobile networks is necessary for uninter-
rupted and continuous operation of the router.
If the
Check Connection
item is set to
enabled
or
e bind
, this activates checking
of the connection to the mobile network. The router will automatically send ping requests to
the specified domain or IP address (
Ping IP Address
or
Ping IPv6 Address
item) at regular
time intervals (
Ping Interval
). In the case of an unsuccessful ping, a new one will be sent after
ten seconds. If this ping a given IP address three times in a row, the router will terminate the
connection and attempt to establish new ones. This checking can be set separate for two SIM
cards. Send an ICMP (ICMPv6) ping 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 the routing table. Therefore, 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
e bind
. The
disabled
option deactivates checking of the connection to the
mobile network.
For routers connected to
Verizon
carrier (autodetected by the router): The retry interval
for connecting to the mobile network prolongs with more retries. First two retries are done
after 1 minute. Then the interval prolongs to 2, 8 and 15 minutes. The ninth and every
other retry is done in 90 minutes interval.
If
Enable Traffic Monitoring
item is checked, the router will stop sending ping requests to
Ping
IP Address
(
Ping IPv6 Address
) and it will watch the Mobile WAN connection. When there is
no traffic during period longer than
Ping Interval
, the router will send ping request to
Ping IP
Address
(
Ping IPv6 Address
).
Item
Description
Ping IP Address
Specifies the ping queries destination IPv4 address or domain
name. Available in IPv4 and IPv4/IPv6
IP Mode
.
Ping IPv6 Address
Specifies the ping queries destination IPv6 address or domain
name. Available in IPv6 and IPv4/IPv6
IP Mode
.
Ping Interval
Specifies the time interval between outgoing pings.
Ping Timeout
Time in seconds to wait for a Ping response.
Table 20: Check Connection to Mobile Network Configuration
4.3.4 Example of Check Connection Configuration
The figure below displays the following scenario: the connection to the mobile network in
IPv4
IP Mode
is controlled on the address 8.8.8.8 with a time interval of 60 seconds for the first
SIM card and on the address www.google.com with the time interval 80 seconds for the second
SIM card. In the case of an active data stream on the router, the control pings are not sent, but
the data stream is monitored.
