Menu path: Setup > Network > LAN Interfaces > [Interface]
Under the name of the individual interface (for example Interface 1), you can overwrite some of the general settings for LAN interfaces. In addition, there are two further settings:
IPv6 configuration
Here, you can choose a configuration type for operation with IPv6. You will find further details in a How-To document.
Network link type
Specify the network link type for the interface. The default is Automatic Recognition.
