How to set up pfSense 2.4.4 with Surfshark

 

In this tutorial, you will learn how to setup Surfshark on your pfSense.

At first, you will need to find Surfshark service credentials. Service credentials are different from your Surfshark account credentials, namely your email address and your password. You’ll need Surfshark service credentials to connect to the VPN using a manual VPN connection.

Here is how you can get your Surfshark service credentials:

  1. Go to this page. This is the page where you can find all the details required for the manual connection.

    You may need to log in before proceeding to this page. In that case, enter your email address and your password, then click Log in.

  2. Click on the Credentials tab on top. You will find Surfshark service credentials there.

    It is a good idea to keep this page open for now. You will need these credentials a bit later.

Choose Surfshark server

Every server location has a hostname that you need to use on pfSense to connect to a particular server.

  1. Switch to the Files section where you will find the list of all servers and their hostnames. Copy the hostname of your preferred location - you will use it a bit later.
