How Do I Configure The SSL-VPN Feature For Use With NetExtender Or Mobile Connect?


Creating an Address Object for the SSL VPN IPv4 Address Range

  1. Login to the SonicWall management GUI.
  2. Click Manage in the top navigation menu
  3. Navigate to Objects | Address Objects and click Add at the top of the pane.
  4. In the pop-up window, enter the information for your SSL VPN Range. An example Range is included below:
    • Name: SSL VPN Pool

      TIP: This is only a Friendly Name used for Administration.

    • Zone: SSL VPN
    • Type : Range

      NOTE: This does not have to be a range and can be configured as a Host or Network as well. To avoid IP Spoof errors and routing issues, we recommend to use a subnet which is not configured anywhere else on the SonicWall. 

    • Starting IP Address:
  5. Ending IP Address:
    • SSL VPN Configuration
      1. Navigate to the SSL VPN | Server Settings page.
      2. Click on the Red Bubble for WAN, it should become Green. This indicates that SSL VPN Connections will be allowed on the WAN Zone.
      3. Set the SSL VPN Port, and Domain as desired.

        NOTE: The SSL VPN port will be needed when connecting using Mobile Connect and NetExtender unless the port number is 443. Port 443 can only be used if the management port of the firewall is not 443. The Domain is used during the user login process. If you want to be able to manage the firewall via GUI or SSH over SSL VPN these features can be enabled separately here as well.

4. Navigate to the SSL VPN | Client Settings page.

The SSL VPN | Client Settings page allows the administrator to configure the client address range information and NetExtender client settings, the most important being where the SSL VPN will terminate (e.g. on the LAN in this case) and which IPs will be given to connecting clients.

CAUTION: NetExtender cannot be terminated on an Interface that is paired to another Interface using Layer 2 Bridge Mode. This includes Interfaces bridged with a WLAN Interface. Interfaces that are configured with Layer 2 Bridge Mode are not listed in the "SSL VPN Client Address Range" Interface drop-down menu. For NetExtender termination, an Interface should be configured as a LAN, DMZ, WLAN, or a custom Trusted, Public, or Wireless zone, and also configured with the IP Assignment of "Static".

5. Click on the Configure button for the Default Device Profile. 

6. Set the Zone IP V4 as SSL VPN. Set Network Address IP V4 as the Address Object you created earlier (SSL VPN Range). 

7. The Client Routes tab allows the administrator to control what network access SSL VPN Users are allowed. The NetExtender client routes are passed to all NetExtender clients and are used to govern which networks and resources remote users can access via the SSL VPN connection.

 CAUTION:All SSL VPN Users can see these routes but without appropriate VPN Access on their User or Group they will not be able to access everything shown in the routes. Please make sure to set VPN Access appropriately.

8. The Client Settings tab allows the administrator to input DNS, WINS, and Suffix information while also controlling the caching of passwords, user names, and the behavior of the NetExtender Client.

9. Input the necessary DNS/WINS information and a DNS Suffix if SSL VPN Users need to find Domain resources by name.

10. Enable Create Client Connection Profile - The NetExtender client will create a connection profile recording the SSL VPN Server name, the Domain name and optionally the username and password.
