I've been trying to setup the ER605 to enable a L2TP VPN connection for a few days now and I'm constantly getting nowhere fast.
Since all the online videos I see for setting up the VPN are through the Omada Controller interface, figured I'd set that up. I found the software installation for it, set it up on my computer (Ubuntu 20.04.3 LTS) and was able to get that up and running. I even went as far as setting up the cloud account and am able to connect to the installation of the Omada Controller on my computer from the cloud.
Where the frustration comes from: The Omada Controller cannot "find" the ER 605 device.
The Omada Controller software is running on my computer and the computer is *literally* plugged directly into the ER 605! Not only that, but the Omada Controller connects to the internet cloud via the internet that it *literally* gets through the ER 605.
So how do I get the Omada Controller to see the device that it is connected to? Furthermore, why do we have to have interfaces that are reliant on "auto-detection" of devices when I could just provide the Omada Controller the IP of the ER 605?
