Connecting Keenetic DSL routers to the Internet via Ethernet
The Keenetic Giga SE (KN-2410) router with DSL modem, besides connecting to the Internet with VDSL or ADSL service, also provide Internet connection via a dedicated Ethernet line.
You can do this by configuring the connection using the Initial Setup Wizard or manually in the web interface (this article covers this option).
Connect to the device web interface, go to the Ethernet Cable Connections to Internet page and click + Add an ISP.

You will see a tab with cable connection settings. By default, port 1
will be assigned to connect a dedicated line from your ISP. In our example, port 4
is assigned to connect the ethernet cable from your ISP.

If necessary, you can change the network port. To do this, select a free port in the Ports and VLANs section and specify Provider for it, which will determine the role of the port as a WAN port.
