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 the 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 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 by takingthe MTU and

subtracting40 bytes for TCP over IPv4.If MTU is set to Auto, 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 MAC addressvia 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.
