Setting up a VPN Server using Untangle Gateway

Today I will show you how to set up a VPN Server using Untangle Gateway.  Untangle Gateway is a dedicated hardware firewall which can be configured in a multitude of ways one of those being as a VPN server.

For the basis of this tutorial I will assume you already have Untangle Gateway installed and configured with the default rack.  If not this tutorial will show you how.

On the default rack shown above scroll down until you come to OpenVPN and click on settings.

On the following screen you will get the option of setting Untangle Gateway as either a VPN server or a VPN client.  Click on VPN server.  This opens up the wizard.  Click next.

To complete the VPN setup you have to configure 2 steps.  Step 1 is your organisation details as shown below.  Once you have entered the required details click next.

Step 2 is to configure a list of hosts or networks that your VPN users will have access to. Your internal network is added by default.  If you wish your users to be restricted to certain servers or workstations this is where you configure it.  For the purpose of this tutorial I will leave this as my internal network.

Once you are happy with the configuration click next.  You will then get the finished screen.

That is your VPN server configured.  We now have to add remote clients.  Untangle Gateway also gives you the option of adding remote networks instead of individual clients.  For the purpose of this tutorial I will add a remote client.

Close down the page to get back to the main page and click on the Clients tab.

On the next page click Add.  This is where you enter the details of the remote client.  My remote client will be called XP1 and I shall leave the Address pool as default.

Once configured click Done.  You will now see that XP1 has been added to the remote client list.

Now click Apply and when applied click ok.  Your server is now set up and XP1 should be able to access your network.

What is a Firewall ?

A firewall is a device designed to permit or deny network transmissions based upon a set of rules. A firewall is frequently used to protect networks from unauthorized access while permitting legitimate communications to pass. Basically a firewall is designed to keep the bad people out while allowing network traffic to function normally.


There are two main types of firewall, either hardware or software based.

Hardware Based

This is when you install the firewall software onto a separate computer and configure it so that it acts as a doorway into your network. The advantage of this method is that any attacker would have to compromise the firewall computer before getting access to any other network resources. The firewall would also protect the entire network not just the computer it is installed on. The disadvantage is that you would require further hardware.

If you are looking for a hardware based firewall then I would recommend using Untangle Linux Firewall. This is open source software which while being easy to set up and configure is also very powerful.

Software Based

This is when you install a piece of software onto the computer that you want to protect. The main advantages of this method are that it is usually easier to setup than a hardware based firewall and does not require any more hardware. The disadvantage of this approach is that the software will take up more system resources and the firewall will only protect the system it is installed on.

Hope this helps.
