USER MANUAL
Peplink Balance Series

14.1 Physical Interface Settings

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
Speed
Balance. In the event of negotiation issues, the port speed can be manually specified. You
can also choose whether or not to advertise the speed to the peer by selecting Advertise
Speed.
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
MTU
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.
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 taking the MTU and
MSS
subtracting 40 bytes for TCP over IPv4.If MTU is set to Auto, MSS will also be set
automatically. By default, MSS is set to Auto.
This setting allows you to configure the MAC address. Some service providers (e.g., cable
MAC
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
address to the original client PC's MAC address via this field. The default MAC address is a
Clone
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.
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
VLAN
provider requires.
Note: leave this field disabled if you are not sure.
