How do I set up my OpenVPN client on my computer?

Accessing your device through Onomondo can be done by setting up an OpenVPN client.

Which program to use?


OpenVPN has their own clients that can be accessed using:

MacOS alternatives

Another free option that is quite popular is called TunnelBlick.

A more advanced option to choose is called Shimo that requires a one-off payment per user. There are others out there that you can test, if you wish.

Windows alternatives

Currently TunnelBlick is for MacOS only and we have not tested other free options. However, for a small fee Vicosity is a popular alternative.

Follow the different guides to install the client of choice.

How do I configure my VPN client?

Adding VPN access to your user

You can turn on VPN access for a user in the Users tab of the Management App and click on the "edit user" button. 


To do this, you will need to be an "admin" user. Otherwise, contact with one of the admin users on the platform to activate it for you. If they don't know how to add VPN, you can send the straight to this section of the article using this url ->

Once you have clicked on the edit user button, you can check the VPN access box and click "Save".


Download/Saving the template configuration file (*.ovpn)

Once activated you will need to download/save the configuration file (*.ovpn)

To get the file you need to: 

  1. access it on our documentation website our documentation under VPN access.
  2. Here,  click the "View More" button, highlight the code and copy it to a new file. Afterwards, save the file as an *.ovpn.

VPN Access

Once downloaded you will need to personalise the config file by completing the missing sections.

Completing the template configuration file (*.ovpn)

To complete the template, you need to acquire your own certificate and private key. The file you receive already contains the Root CA Certificate, as well as the two sections that need you need to fill. Currently, they are represented as a dummy key and cert. Both need to be replaced and can be found under the comment:

# dummy cert and key

The configuration file sections are clearly labelled. The first section requires you to add your own certificate, while the second section is for your private key. If you do not know how to set up your own certificate and private key, contact us at for some help.

Adding the completed configuration file

Once your own certificate and private key has been added to the file, open the VPN client of choice. There will be an option for importing the VPN server configuration. Use the option that asks for a local file. Once that is finished you can log in using the email address you sent us, and the password it uses to log in on Onomondo.

For example, using OpenVPN on mac:

Step 1 - Import from local file. 

Step 2 - Select the completed file.

Step 3 - Connect to Onomondo's VPN.

Step 4 - Sign in using the activated email and your Onomondo password.

How do I access the SIMs once I am connected?

There are different options available depending on your device and how it is set up. No matter the option, you will need the SIMs IP address.

This can be found under the Sims tab on Onomondo.
