Step 2
If your device is supported, please proceed to the Asuswrt-Merlin documentation for installation steps/links:





VPN Install Guide

Step 1
Open the below link in a web browser, this contains our Linux OpenVPN configuration files:




Step 2
With the link in Step 1 open, you will see a list of configuration files, similar to the below screenshot.

You should select the location you want to appear to be in; UK for UK sites, USA for USA sites, etc.

Click on an option name, to download that configuration file.


Which options should I use?!

  • Port 1, 2 are labelled 'Performance', these are typically the fastest
  • Port 3, 4 are labelled 'Fallback', these may be required from some restricted locations
  • We recommend you experiment, to see which works best for you.




Step 3
Now we will upload the configuration file, to your Asus Merlin router

Click VPN, from menu on left hand side, under Advanced Settings




Step 4
Choose OpenVPN Client




Step 5
Under Import ovpn file click Choose File, now choose the file you downloaded in Step 2 - then click Upload.

We strongly recommend you take the time to experiment with both configurations, 'Performance' (UDP) is probably the preferred configuration but 'Fallback' (TCP) can be quicker for some people.




Step 6
Wait until it shows 'Complete', the page will then reload automatically - and the various fields will be configured/populated.


Step 7
Scroll down to 'Accept DNS Configuration' and set to 'Exclusive'


Step 8
Set 'Redirect Internet traffic through tunnel' to 'Yes'


Step 9
Locate Username and Password section, enter your VPN username/password






Step 10
Scroll down again to 'TLS control channel security', set to 'Outgoing Auth (1)'


Step 11
Scroll down to the very bottom of the page, click 'Apply'


Step 12
Now connect the VPN (VPN → OpenVPN Client) by moving the Service State to On




Step 13
You can check if the VPN connected by selecting VPN Status and making sure that OpenVPN Client 1 shows as Running, when you access some web pages you should see the read/write bytes increasing




Step 14
Open the below webpage to verify your internet facing IP address has changed from your ISP to a StreamVia host:
