VPN Unlimited OpenVPN Tomato Router Setup Guide

 1. Getting started:

  • If you are following this guide it means you have no problems connecting to your FlashRouter network and accessing your FlashRouter settings. 
  • If you are having trouble accessing your router settings then you can always follow our guide on how to access your router settings or if needed how to reset your router to default Tomato firmware settings before proceeding with your VPN Unlimited client connection setup. 
  • In order to complete OpenVPN setup for VPN Unlimited, you must first e-mail VPN Unlimited support to obtain the certs, keys, and .ovpn connection files associated with your account. 
  • Hint: Use the program Notepad++ in Windows or TextEdit in MAC OS to open view the contents of your .ovpn file. 

2. Entering VPN Unlimited settings:

In your Tomato FlashRouter settings click on the VPN Tunneling > OpenVPN Client section. 

OpenVPN Client > Client 1 > Basic

Start with WAN

Check this box if you want your VPN connection to startup automatically anytime the router connects to the Internet.

Interface Type




Server Address/Port

At the bottom of the .ovpn file you downloaded above, you can find your server address e.g.: 
remote us-la.vpnunlimitedapp.com

us-la.vpnunlimitedapp.com is your VPN Unlimited server location

Enter port 1194 for Protocol UDP
Enter port 80 for Protocol TCP

Note: There is a lot of copy and paste required for this section. Be sure to have your VPN Unlimited .ovpn file open using Notepad++ on Windows or TextEdit on MAC OS.

Certificate Authority

Copy and Paste all contents in between the <ca> and </ca> lines from your .ovpn file starting and ending with:

Client Certificate

Copy and Paste all contents in between the <cert> and </cert> lines from your .ovpn file starting and ending with:

Client Key

Copy and Paste all contents in between the <key> and </key> lines from your .ovpn file starting and ending with:

Click Save.

Hint: VPN Unlimited Public Client Cert and Private Client Key are DIFFERENT for all VPN Unlimited server locations. If you ever wish to change your VPN server location you need to update the Server IP/Name as well as the Client Cert and Client Key fields. All other settings remain the same.

 Click the Start Now button to start up the VPN Unlimited connection. 

3. Verifying a successful VPN connection:

  1. Instead of seeing the Start Now button, you should now see the Stop Now button in your OpenVPN Client area. Click Stop Now to terminate the active VPN connection at any time. 
  2. Visit http://www.whatismyipaddress.com to verify your new IP address and virtual location. 
    Note: In some cases you may notice that the location is not showing the same location as the server you have input in your router settings; this is because geo tracking tools are often tricked by VPN connections. As long as you see an IP address that is not the same as your normal Internet IP address then you are indeed connected to VPN Unlimited.
  3. Navigate to the Advanced > Routing section in your Tomato firmware settings. If you are connected to a VPN then you will notice a tun11 listed in your Routing Table interfaces (tun12 if you are using OpenVPN Client 2). 

4. Additional Router VPN Features

How can I setup 2 VPN Unlimited client connections on my Tomato FlashRouter?

  1. In the VPN Tunneling > OpenVPN Client section you will see a Client 1 and Client 2 section. It is not possible to run both client VPN connections at the same time, but you can setup both clients and then Start/Stop Now whichever client you like, depending on which VPN server location you want to use. 
  2. Copy all settings used for VPN Unlimited setup as indicated in Client 1 setup above, except this time enter a different server address in the Client 2 > Basic section. 
  3. Make sure you do not check the Start with WAN checkbox on both VPN Clients. If you try to connect to both Client 1 and Client 2 at the same time you will likely lose Internet connectivity entirely. 

5. Backing up your settings:

  1. It is always a good idea to save a backup of your working VPN settings after completing this setup, so that in the result of a reset or faulty settings change you can load your working settings in a few simple clicks.
  2. Go to the Administration > Configuration page and name the file "FlashRouter Backup" for easy searching should you ever need it. Click the Backup button. The file will be saved to your computer.
  3. To load your backup go to the Administration > Configuration, and under the Restore Configuration section, click Choose File, select your backup file, then click Restore and give the router a minute or two to load your settings.
