Choose One-Device > Gateway > Config > VPN> L2TP > L2TP Settings.
Turn on the L2TP function, set L2TP Type to Server, set L2TP server parameters, and click Save.

After you complete Basic Settings of L2TP Server, enable IPsec encryption on the L2TP server to guarantee communication security.

2. Configuring L2TP User

Choose One-Device > Gateway > Config > VPN> VPN Account

Only user accounts added to the VPN client list are allowed to dial up to connect to the L2TP server. Therefore, you need to manually configure user accounts for clients to access the L2TP server.
Click Add. In the dialog box that appears, set Service Type to L2TP or ALL.
(If you select ALL, the created account can be used to establish all types of VPN tunnels.) Enter the username, password, and peer subnet, select a network mode, and click OK.
