11.2 Physical Interface Settings

Physical Interface Settings

Speed

This setting specifies port speed and duplex configurations of the WAN Port.

By default, Auto is selected and the appropriate data speed is automatically

detected by Peplink Balance.

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

This setting specifies the Maximum Transmission Unit.

By default, MTU is set to 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 appropriate MTU value will be

automatically detected. The auto-detection will run each time when the WAN

connection establishes.

MSS

This setting should be configured based on the maximum payload size that the

local system can handle. 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.

By default, MSS is set to Auto.

MAC Address

Clone

This setting allows you to configure the MAC address.

Some service providers (e.g. cable providers) identify the client’s MAC address

and require the client to always use the same MAC address to connect to the

network. In such cases, change the WAN interface’s MAC address to the original

client PC’s one via this field.

The default MAC Address is a unique value assigned at the factory. In most

cases, the default value is sufficient. Clicking the Default button restores 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.

Note: Leave this field disabled if you are not sure.
