L2TP over IPsec is a VPN protocol that combines the Layer 2 Tunneling Protocol (L2TP) with the Internet Protocol Security (IPsec), providing secure data transmission and remote access capabilities.

Please follow the steps below to set up the L2TP/IPSec VPN Server on Deco APP.

1. Launch the Deco app. Go to MORE > Advanced > VPN Server, and tap Add VPN Server.

2. We recommend enabling DDNS (Dynamic Domain Name System) to bind your WAN IP to a domain name. This can prevent issues with your WAN IP changing, which might otherwise cause VPN connection problems.

Please refer to this link:

3. Select L2TP/IPSec, enter the necessary information and save the settings.

  • Description: Enter a name for this VPN.
  • Client IP Address: Enter the range of IP addresses (up to 10) that can be leased to the devices by the L2TP/IPSec VPN server.
  • IPSec Encryption/ IPSec Pre-Shared Key: Keep IPSec Encryption as Encrypted and create an IPSec Pre-Shared Key.
  • Account List: Add the L2TP/IPSec VPN connection account (user name and password) for the remote device. You can create up to 16 accounts.

4. The L2TP/IPsec VPN server is established successfully.
