Step 1

You'll need to access your router's config by entering it's IP address in your browser's (Chrome, Safari, Internet Explorer etc.) address bar. Usually the IP address you need to type is 192.168.2.1 then press enter. Click the image to see what I mean.

Step 2

Once you're in you'll land on the "Status" page.  Now click on the "DNS" link in the navigation menu on the left. You'll be prompted to sign in. By default, my router had no password and all I needed to do to get past the login page was press enter.

Step 4

The router will apply the changes and reboot. The page should refresh once the countdown completes.

Step 3

Once the DNS page loads untick the box next to "Automatic from ISP".

Enter the 2 DNS Proxy server IP addresses from SmartDNSProxy.com here as shown. Then click the "Apply Changes" button. (If you don't know which server to choose, the ones closest to your country are usually the best choice.) I've chosen Sydney & Japan



Step 5

Now go back to SmartDNSProxy.com, login, and check to make sure you're getting all the ticks. You'll probably need to click "Re-Activate" at this stage. Once you have all the ticks, you are done and dusted! Connect your favourite device, and give it a whirl!

WORTH NOTING...

If your ISP (Internet Service Provider) changes your IP address from time to time, or if you lose power or have to restart your router, or if your router is set to automatically restart (sometimes known as smart heal, or first aid) then you'll need to login to SmartDNSProxy.com and "ReActivate" your IP address to get overseas content working again. This only take a few seconds to do. I have added a link to SmartDNSProxy.com to my favourites bar. I've named it "MAKE NETFLIX WORK" so my less technically able family members can fix things if I'm not home :-)
