When Auto-reconnect is selected, the router will automatically attempt to re-establish a
connection if it has dropped.
When Connect-on-demand is selected, the router will only attempt to establish a
connection only when detecting data traffic.
When Connect Manually is selected, it means you need to click the Connect button to dial
up the connection manually. Go to Status > Basic Network > WAN & Uplink tab for
details.
Note – This field is available only when Basic Network > WAN > Physical Interface
> Operation Mode is selected to Always on.
When (0) Always is selected, the selected WAN is in operation all the time. Once you have
set other schedule rules, there are other options to select.
Go to Object Definition > Scheduling for details.
Specify the MTU (Maximum Transmission Unit) for the 3G/4G connection.
Value Range: 512 - 1500, but 0 is for auto.
Uncheck the box to disable NAT (Network Address Translation) function.
When the Network Monitoring feature is enabled, the gateway will use DNS Query or
ICMP to periodically check if the Internet connection is connected.
Choose either DNS Query or ICMP Checking to detect a WAN link.
With DNS Query, the system checks the connection by sending DNS Query packets to the
destination specified in Target 1 and Target 2.
With ICMP Checking, the system will check the connection by sending ICMP request
packets to the specified destination.
