This document explains how to configure the iPhone L2TP Client access to the SonicWALL WAN GroupVPN SA using the built-in L2TP Server.

This guide is for SonicOS Enhanced 5.2.x or higher for NSA devices & 4.2 and higher for PRO devices. This guide is intended to be followed AFTER configuring your L2TP services on the SonicWALL (instructions here).

STEP 1: From the Home Screen, press the Settings icon


STEP 2: Next, select General from the Settings menu.


STEP 3: From the General menu, select Network.


STEP 4: In the Network menu, select the VPN option.


STEP 5: In the VPN menu, choose the heading titled, Add VPN Configuration


STEP 6: In the Add Configuration menu, make sure L2TP is selected.


STEP 7: Fill out the Required fields, then press save when you are done.

Description: This is a friendly name for your VPN configuration.
Server: This is the WAN IP address of your SonicWALL
Account: This is the user account created for accessing the network via VPN
RSA SecurID: Not used in this configuration.
Password: If left blank, every time a connection is established, a prompt for your password will appear. If completed, then the iPhone will store your password for future connections.
Secret: This is your pre-shared secret for your VPN connection.
Send All Traffic: This will allow for either split tunnel or route-all depending on VPN configuration. This example will use the route-all config.

STEP 8: The saved configuration will appear on the VPN screen. You can then slide the VPN to the “ON” position, and your iPhone will begin IPSec communication.


STEP 9: When completed, you will see a message in the SonicWALL logs confirming VPN authentication.
