Settings – Port Options
Interface
•
WAN Port
– Select a particular WAN port from the pull-down menu to
setup WAN port configuration.
•
MTU
– The Maximum Transmission Unit for the Ethernet data. This
is used to determine the packet size to be used on the WAN
interface. Normally, this does not need to be changed but if your ISP
advises you to use a particular MTU, enter it here. The default MTU
value is 1500 Bytes.
Connection Health
Check
•
Method
– There are three methods available for checking if a WAN
port is alive or not
.
Multiple choices can be selected when using it.
•
Disable
will not perform an Alive Indicator Check. By default, Health
Check is set to
Enable
. If the “Alive Indicator” input box is left blank,
Health Check performs an ICMP echo packet request to the specific
destination. This could be either a URL or an IP Address specified
by users in the “Alive Indicator” input box or WAN interface
gateway.
•
Interval
– The interval time for device health check. The default
interval time is 60 seconds.
•
Alive Indicator
– This is the IP address used to check if the WAN
connection is operating. The Multi-WAN VPN Link Balancer will
contact this system to check if the WAN connection is working or
not. You may change this address if you wish. Default is the
gateway IP.
Note
: This is not used for PPPoE connections.
Transparent Bridge
Option
•
Bridge Mode
– If set to
Enable
, this WAN port doesn’t use NAT &
Load Balance function when the LAN/WAN IP have the real IP
addresses on the same network segment.
•
NetBIOS Broadcast
– If you enable the NetBIOS Broadcast, this
will allow you to access files through the Microsoft network
neighborhood.
Transparent Bridge
Options (For all
interfaces)
•
Traffic Management
–
Strict Binding:
Traffic from bridge hosts (eg. transparent to
WAN1) can only go through the specified WAN interface
(eg. WAN1).
Loose Binding:
This acts as a failover mechanism for transparent
bridge mode.
T
raffic from bridge hosts (eg. transparent to
WAN1) can go through any WAN interface (eg. WAN2 or
other) when bind interface (eg. WAN1) is down.
Load Balancing:
This acts as a load balancing mechanism for
transparent bridge mode. Traffic from bridge hosts (eg. transparent
to WAN1) can go through any WAN interface (eg. WAN1, 2 or
other) based on the loading mechanism specified in the load
balance section.
•
ARP Table
–
The
ARP Table is used by the device to determine
the bridge hosts’ location (e.g. inside/outside WAN and which
WAN). Its size can be adjusted if needed.
View ARP Tables
displays ON/OFF selection of bridge mode on each WAN port.
Clear ARP Tables
disables bridge mode on all WAN ports.
