I also have been using netmaker for a time now and it worked flawlessly on linux OS systems. I am using it on edge devices also, and noticed that the netclient does not work as expected im combination with network-manager. I use network-manager to configure my LTE (wwan0) connections, it is so much easier and reliable than having it to configure through the QMI tools. However, after some troubleshooting, netclient does not go very well with network-manager. The netclient connects to the netmaker server, but after one minute I cannot ping from my edge-device any more. I think network manager needs additional configuration which I don't know at this time. I now uninstalled network-manager and disabled the modem-manager service and configured the connection manually, all is well again. Does anyone have the same experience with netclient in combination with network-manager and has a solution/workaround? I am using v0.17.1 on raspbian 64-bit and netclient does work well without network-manager, but not with apparently.
