Asuswrt-Merlin - PPTP

Here you can find setup information for your chosen VPN and also how to fix any problems you might encounter.

You can use the Table of Contents on the right hand side of this window to navigate between the different sections.

Introduction - please read

This guide assumes that your Asus router will be a dedicated secondary VPN router, your main/ISP router will continue to provide non-VPN internet access - the Asus router will connect to your main/ISP router to get its internet connection, your main/ISP router will continue to connect to your ISP/broadband.

Upgrade to Asuswrt-Merlin

Step 1
Verify that your Asus router is supported by Asuswrt-Merlin, the below devices are fully supported at the time of writing, but PLEASE double check on the Asus Merlin website (link in Step 2 below).

Asuswrt-Merlin officially supports the following router models:

  • RT-AC66U_B1 (same firmware as the RT-AC68U)
  • RT-AC68U (including revisions C1 and E1)
  • RT-AC68P (same firmware as RT-AC68U)
  • RT-AC68UF (same firmware as RT-AC68U)
  • RT-AC87
  • RT-AC3200
  • RT-AC88U
  • RT-AC3100
  • RT-AC5300
  • RT-AC1900 (same firmware as RT-AC68U)
  • RT-AC1900P (same firmware as RT-AC68U)
  • RT-AC86U (starting with version 382.1)
  • RT-AC2900 (same firmware as RT-AC86U)
  • RT-AX88U

(Note: the U, R and W variants are all supported, as they are the exact same hardware and firmware, only different marketing SKUs or different case color)

The following models are no longer officially supported:

  • RT-N16
  • RT-N66U
  • RT-AC66U
  • RT-AC56U

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

VPN Install Guide

Step 1
Retrieve the Server Address for the VPN you want to connect to, i.e the location you want to appear to be in, you will need this later:

Step 2
Connect the blue WAN/Internet port, from your Asus router to your main broadband routers cabled ports (there are usually 4 grouped together) if you not already done.

Setup your new wireless network (this wireless network will provide VPN access, your main/ISP router will continue to provide non-VPN internet access) making sure to specify WPA/WPA2 encryption keys, so that it is NOT an open network (otherwise all your neighbours will be able to use your VPN).

Step 3
Click WAN, from menu on left hand side, under Advanced Settings

Step 4
Configure as per the Basic Config, WAN IP Setting, WAN DNS Setting sections as follows:

Step 5
Configure the Account Settings as follows, the 'PPP username' is your VPN username and 'Password' your VPN password:

Step 6
Configure the 'Special Requirements from ISP' section as follows, the 'VPN Server' is the server address you want to connect to (where you want to appear to be) retrieved in Step 1 of this Install Guide:

Step 7
Click 'Apply' at the bottom of the window to save the configuration

Step 8
Give the device a few minutes to connect the VPN, make sure your device(s) is connected to the Asus wireless/wired ports, then open our tester page below to make sure you're successfully connected.

Other Information

Poor Performance

We ensure our servers are NEVER overloaded, so this is not the issue if you are receiving poor performance; please get this out of your mind now ;-)

Your network, your ISP and their network have as much an impact on the speed you will receive as we do. Some of you will be connecting to a VPN server half way around the world, so degradation along the way is inevitable.

Quick tips

  • Experiment with Location 1, Location 2 (Site 1, Site 2) etc connections
  • Experiment with Option 1 UDP vs Option 2 TCP connections
  • If Faster does not connect, or is slow, try changing the port.
  • Use a network cable not wireless/wi-fi, this can often make the biggest difference.
  • Reboot router/computer
  • Clear all browser cookies/history/cache
  • If you are a VPN All or VPN UK & USA member and are using StreamVia to access streaming TV/video, please try SmartStream instead.

Location 1, Location 2 (Site 1, Site 2) etc
Each different VPN Site is a separate VPN location, you should experiment to see which works best for you. There may be a massive difference, some difference or no difference for you in speed. But you should experiment to see ;)

Option 1 UDP vs Option 2 TCP connections
Please ensure you experiment with both, whilst Option 1 has the capability of being faster than Option 2 there are some cases when Option 2 can actually work out best for you.

Change Port
If your ISP rate limits certain ports (to try to disrupt the VPN) you can try adjusting the port number to see if you can get around this. Click to see how to change the port.

Browser cache/cookies
Always clear your browser cache/cookies/history after connecting VPN, you need to reset the browser for your change in location. Failure to do so can result in poor performance.

Wi-fi vs wired ethernet
Using a wired connection instead of wireless often has the biggest impact on speed. The best speed and reliability with always be seen when using a network cable rather than wireless, wireless networks cause latency which causes the speed to drop. If you are having speed issues, please try with a network cable rather than wireless.

Your broadband
Just because you have XYZ speed broadband, does not mean you should expect this speed over a VPN. All networks deteriorate in speed the further away you are, so whilst someone connecting in the UK or a country close by will be able to achieve close to maximum speed to a UK server, those in Australia will not.

Also, if you or someone else is heavily using the broadband connection (even if not over the VPN) then you will notice a performance drop. For best performance ensure others are not downloading/streaming on the same connection as you.

Reboot everything
Try restarting both your computer and your broadband router, sometimes this can work wonders!

Alternative DNS
For best performance - especially from China, UAE etc - we recommend that you configure alternative DNS servers on your computer, as some countries will filter DNS which can cause problems for your connection ie inability to connect at all, or unstable connections with frequent disconnects. You need to configure these on your wireless or ethernet adapter - ie the physical network interface you use to connect to your network - details are contained in the below links:
