Application scenario

Take the following topology as an example, we will configure (Router A) as PPTP&L2TP VPN Client to connect the PPTP&L2TP Server (Router B).

Configuration steps:

Step 1. Configure the PPTP&L2TP VPN server.

For detail configuration, please refer to the following link:

PPTP&L2TP VPN server in controller mode:

Step 2. Configure the PPTP&L2TP VPN client separately.

For both L2TP&PPTP VPN client, please go to “Settings>VPN>Create New VPN Policy”, and input the information from PPTP&L2TP VPN server.

Note:

Username /Password: the user information created on VPN Server

Remote Server: WAN IP of VPN Server

Remote Subnet: the LAN Subnet of VPN Server which you can access via VPN connection

Local Network: Clients which are able to access the VPN Tunnel in LAN Subnet of VPN Client

Pre-shared Key: the password created on VPN Server

Note:

Username /Password: the user information created on VPN Server

Remote Server: WAN IP of VPN Server

Remote Subnet: the LAN Subnet of VPN Server which you can access via VPN connection

Local Network: Clients which are able to access the VPN Tunnel in LAN Subnet of VPN Client

For “Working Mode”, please check the explanation below:

NAT: NAT (Network Address Translation) mode allows the device to translate source IP address of L2TP packets to local IP address of L2TP tunnel.
Route: Route mode allows the device to forward L2TP packets via routing protocol.

Step 3: Connect the PPTP&L2TP VPN client to PPTP&L2TP VPN servers and verify the connection.

1. Please go to “Insight>VPN Status” to check the tunnel list for both PPTP&L2TP VPN server and client.

2. Try to ping the LAN IP from VPN server (Router B) on VPN client (Router A), it would get reply from VPN server.

The above two methods mean the VPN tunnel establishes successfully between the VPN client and VPN server.
