We support many VPN poviders with our FlashRouters. You can see a complete list of our supported providers on our VPN Routers page.
Don't see your provider on our list? It may not be one that we support yet. We would be happy to test it for you to make sure it is compatible with the open source firmware we use.
You can contact our support team via email at firstname.lastname@example.org and if you provide them with the .ovpn files and your VPN account Username and Password, they can test it for you.
