IMPORTANT NOTE: The NCP Client (or derivative thereof, also referred to as NCP Client in this document) cannot co-exist with another VPN Client, so it
is imperative that other VPN clients have been removed before
proceeding. You will be able to use the NCP VPN Client to establish
connections to many other VPN Gateways, and are by no means locked down to only using specific vendor's VPN gateways.

SonicWALL Setup

Click on the VPN button on the left and the following is displayed:

Write the Firewall Unique Identifier down (You will need this later in the NCP setup).

Click on “Configure”

Set a shared secret on this page. Make note of this also for the NCP client setup later in this post.

Click advanced:

IMPORTANT: Make sure perfect forward secrecy is checked.             

NCP Secure Client Configuration

Next we will configure the NCP client for connection:

In the NCP Client click Configuration > Profile Settings

Choose New Entry and follow each of the prompts with what is displayed below:

Give the connection a freindly name so that you can easily identify it.

The LAN selection is proper for most installations. If you use ISDN or Dial up then
you will need to make a different choice above.

Enter your shared secret that you recoded earlier and repeat it in the confirm box to
the left. For local identity put the unique identifier in that you recorded in the SonicWALL
setup section.

Click Finish.

Click Connect

A successful connection looks like this.
