I try to configure ER605 router (without omada controller) as L2TP VPN client. VPN server is running on windows 2019 server. Windows clients one by one can connect to windows server but with the ER605 I can not to stabilize the connection. When L2TP client settings is done then IPsec policy window shows correct datas but L2TP tunnel list sray empty. Internet connection works well via the router on the LAN ports. I tried to reset and tried with available firmwares but does not work. (the same setting also works on TL-R600VPN)

- Is it possible that I need to use omada controller if I want to set router as VPN client?

- Have you any advices or idea?
