Description
Connection Control
Required setting
There are three connection modes.
Auto-reconnect
enables the router to always keep the Internet
connection on.
Connect-on-demand
enables the router to automatically re-
establish Internet connection as soon as user attempts to access
the Internet. Internet connection will be disconnected when it has
been inactive for a specified idle time.
Connect Manually
allows user to connect to Internet manually
.
Internet connection will be inactive after it has been inactive for
specified idle time.
Note
: If the WAN interface serves as the primary one for another WAN
interface in Failover role (and vice versa), the Connection Control
parameter will not be available on both WANs as the system must set it to
“Auto-reconnect”
Maximum Idle Time
1. Optional setting
2.
600
seconds is default
Specify the Maximum Idle Time setting to disconnect the internet
connection when the connection idle times out.
Value Range
:
300 ~ 86400.
Note
: This field is available only when
Connect-on-demand
or
Connect
Manually
is selected as the connection control scheme.
MTU
1. Required setting
2.
Auto(0)
is set by
default
3. Manual set range
1200~1500
MTU
refers to Maximum Transmission Unit. It specifies the largest packet
size permitted for Internet transmission.
When set to
Auto
(value ‘0’), the router selects the best MTU for best
Internet connection performance.
NAT
1. Optional setting
2. NAT is enabled by
default
Enable NAT (Network Address Translation) on the WAN connection.
Uncheck the box to disable NAT.
IGMP
1. Required setting
2. Disable is set by
default
Enable IGMP (Internet Group Management Protocol) to enable the router
to listen to IGMP packets to discover which interfaces are connected to
which device. The router uses the interface information generated by IGMP
to reduce bandwidth consumption in a multi-access network environment
to avoid flooding the entire network.
WAN IP Alias
1. Optional setting
2. Box is unchecked by
default
Enable
WAN IP Alias
then enter the IP address provided by your service
provider.
WAN IP Alias
is used by the device router and is treated as a second set of
WAN IP to provide dual WAN IP address to your LAN network.
Network Monitoring
1. Optional setting
2. Enabled by default
When
the Network Monitoring feature is enabled, the gateway will use
DNS Query or ICMP to periodically check Internet connection status.
Choose either
DNS Query
or
ICMP Checking
to detect 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 connection by sending
ICMP request packets to the destination specified in Target 1 and
Target 2.
Loading Check
Enabling Loading Check allows the router to ignore unreturned DNS
Queries or ICMP requests when WAN bandwidth is fully occupied.
This is to prevent false link-down status.
