Jan 26, 2018 The Cisco AnyConnect VPN Client software package is pushed from the SSL VPN gateway to remote clients when support is needed. The remote user (PC or device) must have either the Java Runtime Environment for Windows (version 1.4 later), or the browser must support or be configured to permit Active X controls.

I have used Dell’s SonicWALL firewalls at several employers. From TZ190’s to NSA 3600’s. I am no expert on SonicOS or SonicWALLs in general, but I have been either the I.T. person who made the decision to use them, or I have had administrative access to them so I could perform maintenance. I’m much more experienced at the Windows server and desktop level.
It’s relatively easy to connect a Windows machine/client, to a SonicWALL firewall using their free Global VPN Client. But it’s always been a headache to connect a Mac OSX computer, to a SonicWALL firewall. Well let me take that back. It’s relatively easy to use equinux’s VPN Tracker to connect to a SonicWALL. Somehow VPN Tracker “just works” with little configuration. But it also costs $60.00 to $70.00 per license/computer. If you work for a large organization, buying VPN Tracker for your Mac VPN Connectivity needs, should be a no-brainer. But for those of you who work for smaller companies who question a lot of expenses, and you have Mac computers, then Lobotomo’s free IPSecuritas VPN Client may be for you. If it works out for you, I do encourage you click their Donate button and give what you can.
It took me quite awhile to finally get IPSecuritas working with the latest SonicWALL firewall I’ve been connecting to, an NSA 3600. The firmware version on the SonicWALL I’m using is SonicOS Enhanced 6.2.2.2-19n. Your settings may differ if you are using a different SonicWALL or a different firmware version – but things should be similar, in the same classes of firewalls. And the IPSecuritas version I’m using is V4.6.1.
I read several guides, and tried countless combinations of settings. I credit the following guides, for getting me started:
- The basic IPSecuritas to SonicWALL V3 guide
- wimpog’s blog reply on SonicWALL NSA 2400 VPN
- a blog post by kleetus on SonicWALL enhanced firmware
- Sean LaBrie’s article on Configuring IPSecuritas for Use with a SonicWall TZ190 Enhanced
- And a somewhat unrelated blog post on Connecting a Mac to a SonicWALL via LT2P
All of the above are somewhat old articles, often referencing much older versions of SonicOS firmware or the IPSecuritas client itself.
Most of the above articles attempt to explain their settings by describing the settings/options to select. And the problem is, with older versions of the firmware or IPSecuritas client, some of the settings/options have changed and it’s a bit difficult to understand some of what is described.
I’m going to show you the setup primary via screenshots. With some descriptions only going into detail about options that may differ on your setups.
Keep in mind that what worked for me, may not work for you. Plus, you really need to have administrative access to your SonicWALL, or know the I.T. person who does, who can help you sort this out.
SONICWALL SETUP
VPN > SETTINGS MENU
On this page, click the Edit link to the right of WAN GlobalVPN. See below:
VPN > SETTINGS > GENERAL
Change the “Shared Secret” from yourpresharedkey to a key that you choose. See below:
VPN > SETTINGS > PROPOSALS TAB
Ensure your settings are the same as below:
VPN > SETTINGS > ADVANCED TAB
Set your Advanced tab options as per below. However it’s important to note that if your SonicWALL is configured to make people login with a SonicWALL Username/Password, then your “Require authentication of VPN clients by XAUTH” must be checked, and the “Use Group for XAUTH users” is probably “Trusted Users”.
This means that in the “Users” section of SonicWALL, each User under “Local Users” must be configured on the “Groups” tab, to be a member of “Trusted Users”. There may be other configurations necessary in the Local Users section.
VPN > SETTINGS > CLIENT TAB
One important change I made here, was to change “Virtual Adapter settings” from simply “DHCP Lease” to “DHCP Lease or Manual Configuration”. With just “DHCP Lease”, my IPSecuritas would not complete the connection.
I also enabled “Use Default Key for Simple Client Provisioning”
VPN > ADVANCED
I’m not sure if there were any changes on this page. Set as per below:
VPN > DHCP over VPN
Click “Central Gateway” and then click “Configure”. Make sure your options are set the same as below:
IPSECURITAS SETUP
GENERAL TAB
Create a new connection (sample here is “Test Connection” and under the General tab, put your IP address in place of “yoursonicwall-IP”. Set other options as below.
However note that if your IP Address range, where you are connecting to, is different than 192.168.1.#, then you should specify the correct subnet.
PHASE 1 TAB
Set your Phase 1 as below:
PHASE 2 TAB
Set your Phase 2 as below:
ID TAB
Set the fields in your ID tab as below. But under Remote Identifier change “yoursonicwallID” to match the “Unique Firewall Identifier” you specified on your SonicWALL under VPN > SETTINGS
On your SonicWALL under VPN > SETTINGS > ADVANCED TAB > CLIENT AUTHENTICATION, if you clicked the Check-Box next to “Require authentication of VPN clients via XAUTH” then be sure to select “XAuth PSK” on the IPSecuritas “ID” tab below. If you didn’t select that checkbox, then you need to match the alternative authentication methods that you used on your SonicWALL – or you will not be able to connect.
Assuming you seelcted XAuth PSK above, then specify the same Preshared Key that you specified on your SonicWALL under VPN > SETTINGS > [Edit] WAN GROUPVPN > GENERAL TAB > SHARED SECRET FIELD
In the Username field, specify the same “Name” field you specified on your SonicWALL under USERS > LOCAL USERS
DNS TAB
Under “Domains” replace “yourdomainname” with your local network Domain Name, assuming you have one.
Under Name Server Addresses, specify the IP Address of your internal DNS server, assuming you have one.
If you do not have an internal DNS server, I assume you remove the checkmark next to “Enable”. I’ve always had internal DNS servers so I’m not sure what effect, removing this will have.
OPTIONS TAB
Set your checkboxes to match those below.
Note that most IPSecuritas and SonicWALL help sites I’ve read, say to also select “Disable” next to NAT-T. However for my circumstances, I found that I had to “Enable” NAT-T, in order to subsequently be able to connect to my servers via Windows Explorer and specifying their #.#.#.# IP address, or to use Remote Desktop for that matter.
FINAL NOTES
Remember that every situation is different. You may have some SonicWALL settings that are slightly different, which could mean your IPSecuritas will not connect, if it’s settings don’t match the SonicWALL.
If it doesn’t work, y best advice, read the other older articles I linked to above, in addition to mine, and try and find the culprit!
I wish you the best of luck!

Overview
Secure Sockets Layer (SSL) VPN is an emerging technology that provides remote-access VPN capability. SSL VPN has some unique features when compared with other existing VPN technologies. Most noticeably, SSL VPN uses SSL protocol and its successor, Transport Layer Security (TLS), to provide a secure connection between remote users and internal network resources.
Tunnelblick is use to established vpn connection from MAC OS system.
Tunnelblick is an open source graphic user interface for SSL VPN on Macintosh (Mac) OS X. It comes as a ready-to-use application with all necessary binaries and drivers. It does not require any additional installation. You just need to add the VPN tunnel configuration and encryption information. Tunnelblick Client can be used to establish SSL VPN connection between Mac OS and UTM.
Scenario
Prerequisite
This configuration consists of two (2) sections.
1. UTM Configuration
2. MAC OS X Configuration
1. UTM Configuration
We will have to create four VPN rules for establishing VPN in either inter-zone or custom rule.
A. LAN -VPN
B. VPN-LAN
C. UTM-VPN
D. VPN-UTM
- Select services as per your requirement or you can select any services and click on OK.
Configuring SSL VPN Server Settings
Before establishing SSL VPN connections you need to configure the SSL VPN server on Seqrite UTM. The client will send request to this server and the server will authenticate the client as per the authentication settings. After a successful authentication the connection for communication will be established.
1. Navigate to VPN > SSL > Server Settings. The following screen appears.
2. Select a Certificate Authority for SSL VPN and set it as default using the Set Default button. If there is no Certificate Authority, you can also create a certificate using the ADD(+) button.
