Field
Description
Speed
Specifies the speed and duplex configurations of the WAN Port.
By default,
Auto
is selected and the BD1000 automatically detects
the appropriate data speed.
In the event of negotiation issues, the port speed can be manually
specified to circumvent the issues. You can also choose whether or
not to advertise the speed to the peer by selecting the
Advertise
Speed
checkbox.
MTU
Specifies the Maximum Transmission Unit. Default =
Custom 1440
You may adjust the MTU value by editing the text field. Click
Default
to restore the default MTU value. Select
Auto
and the
BD1000 will automatically detect the appropriate MTU value. The
auto-detection will run each time the WAN connection establishes.
MSS
Configures the maximum payload size that the local system can han-
dle. The MSS (Maximum Segment Size) is computed from the MTU
minus 40 bytes for TCP over IPv4. If MTU is set to Auto, the MSS will
also be set automatically.
Default =
Auto
MAC Address Clone
Specifies the MAC address. Some service providers (e.g. cable pro-
viders) identify the client’s MAC address and require the client to
always use the same MAC address to connect to the network. In
these cases, use the
MAC Address Clone
field to change the
WAN’s MAC address to the original client PC’s MAC address.
The default MAC Address is a unique value assigned at the factory.
In most cases, the default value is sufficient. Click the
Default
button
to restore the MAC Address to the default value.
VLAN
Some service providers require the router to enable VLAN tagging
for Internet traffic. If it is required by your service provider, you can
enable this field and enter the VLAN ID that the provider requires.
Default =
Disabled
