This article details how to setup the SSL VPN Feature for NetExtender and Mobile Connect users, both of which are software based solutions.

NetExtender is available for the following Operating Systems:

• Microsoft Windows
  
• Linux Distributions

Mobile Connect is available for the following Operating Systems:

• Windows 8.1 & 10
• OS X
• iOS

RESOLUTION FOR SONICOSX 7.0

This release includes significant user interface changes and many new features that are different from the SonicOS 6.5 and earlier firmware. The below resolution is for customers using SonicOSX 7.0 firmware.

Creating an Address Object for the SSL VPN IPv4 Address Range

• Login to the firewall management UI.
• Click Object in the top navigation menu.
• Navigate to Match Objects |Addresses and click Add at the top of the pane.

NOTE :- Please make sure to create the SSL VPN pool Address object in a  completely different subnet ( Different from Azure-VNET/AWS-VPC).

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.

   

SSL VPN Configuration

• Navigate to the  Network |SSL VPN | Server Settings .
• Navigate to SSL VPN STATUS ON ZONES which represents SSL VPN Access status on each Zone.
• Enable or disable SSL-VPN access by toggling the zone below. The Green indicates active SSL VPN status.
• Navigate to SSL VPN SERVER SETTINGS,  Select the SSL VPN Port, and Domain as desired.

• Navigate to the Network|SSL VPN|Client Settings and Select configure Default Device Profile.

• Set the Zone IP V4 as SSL VPN and Network Address IP V4 as the Address Object you created earlier.

• 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.

• 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 to access domain resources by name.

• 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.

Adding Users to SSL VPN Services Group

NetExtender Users may either authenticate as a Local User on the SonicWall or as a member of an appropriate Group through LDAP.

On the Groups tab add SSL VPN Services to the Member Of: field.

• On the VPN Access tab add the relevant Subnets, Range, or IP Address Address Objects that match what the User needs access to via NetExtender.
   NOTE: SSL VPN Users will only be able to access resources that match both their VPN Access and Client Routes.

• Click on Save and close the window.
  

Navigate to the Object|Action Profiles|Security Action profile and add Security Action Profile  "SSLVPN" (Enabling Interested Security Services).

Navigate to the Policy|Security Policy and add Security Policy Rule "SSLVPN Allow" with Source as "SSLVPN" and Destination as "LAN" to allow interested Traffic.
