Testing Your VPN ConnectionFirst, without having a VPN connection enabled, open a browser and go to DNSLeakTest.
The site will return the IP address assigned by your internet service provider and as you appear to the rest of the world. To check your DNS settings through the same website, click on Extended Test and it will tell you which DNS servers you are using.
Now connect the OpenVPN client to your Droplet's VPN and refresh the browser. The completely different IP address of your VPN server should now appear. That is now how you appear to the world. Again,DNSLeakTest's Extended Test will check your DNS settings and confirm you are now using the DNS resolvers pushed by your VPN.
