This article will walk you through configuring WAN GroupVPN in NSSP 13700 for connecting with Global VPN Client

Resolution

Configure WAN Group VPN on the SonicWall

1. Login to the SonicWall management GUI.
2. Click Network in the top navigation menu.
3. Navigate to IPSec VPN | Rules and Settings.
4. Ensure that the Toggle switches for Enable VPN under the Settings tab and the WAN GroupVPN under Policies tab are enabled.
   
   
   
   
   
5. Click configure icon for the WAN GroupVPN entry. The VPN Policy window is displayed.
   
   
   
6. In the General tab, IKE using Preshared Secret is the default setting for Authentication Method. Enter a Shared Secret in the Shared Secret field. A default auto-generated Shared Secret should auto-populate and can be used if you prefer.
   
   
   
7. Click the Proposals tab, use the default settings or choose the desired Encryption and Authentication options for Phase 1 and Phase 2 proposals.
   
   
8. Click the Advanced tab and select the user group for XAUTH. 
   
   Require Authentication of VPN Clients via XAUTH- When enabled all the users connecting to the corporate network are authenticated. Unauthenticated traffic will not be allowed to connect. Trusted users’ group is selected by default.
   
   Management via this SA- Optionally, if you want the Remote users to manage the SonicWall security appliance. Select the management method, either HTTP or HTTPS.
   
   
   NOTE: Want to use LDAP instead of Local Users? You can change Trusted Users to a Group you've imported from LDAP. Even if you don't all LDAP Groups will inherit both Trusted Users and Everyone, so you can have both Local and LDAP Users connect at once.
   
   
9. Click the Client tab, select the following settings in the image below.
   
   
   
10. Click Save  and close the window.
    
    

Configure DHCP over VPN

1. Navigate to IPSec VPN | DHCP over VPN and select Central Gateway from the menu.
2. Click Configure. The DHCP over VPN Configuration window is displayed.
   
3. Select the appropriate options for your configuration.  Refer to the information below for more details. 
   
   
   Use Internal DHCP Server- Enables the SonicWall to be the DHCP server for either the Global VPN Client connections to this SonicWall or for Remote firewall connections via VPN.  For this example, we would only be concerned with the Global VPN Client (GVC).
   
   Send DHCP requests to the server addresses listed below- Enables the SonicWall to forward DHCP requests to the server indicated below in the IP Address Field.
   
   NOTE: You will need to separately add the DHCP server using the ADD button
   
   Relay IP Address (Optional)- If set, this is used as the DHCP Relay Agent IP address (giaddr) in place of this SonicWall's LAN IP address. This address is only used when no Relay IP Address has been set on the Remote Gateway and must be reserved in the DHCP scope on the DHCP server.
   
   
4. Click OK.

Configure User Accounts 

1. Navigate to Device | Users | Local Users & Groups. Click Add User.
2. Under the Settings tab enter the desired Name and Password.
   
   
   
3. In the Groups Tab ensure the user is a member of Trusted Users or select a different local user group or LDAP group in which the user is part of.
   
   
   
4. From the VPN Access tab, select the Address Objects or Address Groups that the user needs access to and add to the user's access list.
   
   
   
5. Click Save.
