M2M Cellular Gateway
Manually: This gateway won't start to establish WAN connection until you press "Connect"
button on web UI. After normal data transferring between LAN and WAN sides, this gateway will
disconnect WAN connection if idle time reaches value of Maximum Idle Time.
Please be noted, if the WAN interface serves as the primary one for another WAN interface in
Failover role, the Connection Control parameter will not be available to you to configure as the
system must set it to "Auto‐reconnect (Always on)".
Auto‐reconnect / Dial‐on‐demand / Manually Scenario:
As an example, WAN‐1, WAN‐2 and WAN‐3 are all Ethernet interfaces with "Always on" operation
mode. Their WAN Type is set to "Dynamic IP" but with different Connection Control approaches.
WAN‐1 uses "Auto‐reconnect (Always on)", WAN‐2 uses "Dial‐on‐demand" and WAN‐3 uses
"Manually". Following 3 tables list the parameter configuration for these three WAN interfaces.

Connection Control
System keeps alive the WAN connection whose connection control is "Auto-reconnect
(Always on)". After system booting up, the connection will be alive and once the
connection is down, system will re-connect it. The scenario is shown in following diagram.
