Troubleshoot Tuesday: Setting Up Multi-Step OpenVPN In Your VPN Accelerator

Here at Sabai Technology, we’re always posting about how to set up your OpenVPN configuration in your router, but what about in your VPN Accelerator?  Sometimes using a VPN company that has multiple files and/or a username/password setup can get a little tricky.  We’re working on custom instructions for all of our companies and exactly what needs to be done for them, but until then, how about this little bit of information?  IpVanish, PureVPN, TrilightZone, IbVPN, Express VPN, and SmallVPN all currently require extra files other than just a .ovpn file, and/or require a username.  If you’re having issues setting up your Accelerator with any of these companies, rest assured you’re not the first.  While all of these companies are a little different, here is the basics of what you will need to get your Accelerator running seamlessly.

Setting up Accelerator with Multiple Files

  1. Get all of the files you need from your VPN Provider.  If you do not currently know how to access those files, please see the instructions that came with your router or find your instructions here.
  2. Make sure if your files come in a Zip file that you have unzipped to a place that will be easy to find.
  3. Go to http://wizard.sabaitechnology.com/.
  4. Once there, click on OpenVPN.
  5. Browse to the .ovpn file for the server of your choosing.
  6. Click Sabai OS.
  7. Double check that information and make sure it is accurate then click convert.
  8. Once there, it will ask for the other additional files needed.  It could just be one file, or it could be four other files like required in this example. Those files should be in the same file as the original .ovpn file you used.
  9. Once all the files have been uploaded, click Convert.  This will download a file to your computer right away.  Normally into your downloads folder. This file has combined all required files into one .ovpn file that can be used in the Accelerator.
  10. Log into your Accelerator at
  11. Go to OpenVPN
  12. Upload the file you just downloaded from the Wizard.
  13. If your VPN Provider requires a username and password, please refer to the below instructions before starting the VPN.  You will have a few additional steps to follow before your VPN will start.  If your VPN Provider does not require a username and password, such as Express VPN and Small VPN, you can just press start here and the VPN should start up with no issues.

Setting up Accelerator with Username and Password

We have previously done a segment on this, with the instructions here: http://blog.sabaitechnology.com/category/vpn-accelerator/
hose instructions should work just fine for your setup, but a few note on this.  When you copy and paste the below code, take out the ” ” and reenter them.  The formatting will not be correct if you just paste straight into the Accelerator.

exec 2>&1

echo -e “username\npassword” > /home/dumbroot/myauth.txt

We understand this is quite advanced, but we have a lot of customers who would much rather do it without having to make an wait for an appointment with our Tech team.  If that is the case, feel free to use these instructions to get you all set up!  Having problems or questions?  Reach out to us at support@sabaitechnology.com!

Troubleshoot Tuesday: Username & Password on the VPN Accelerator

This year, we released OSv5, which expanded Sabai OS’s ability to work with VPN providers which required an external username and password. This was a great addition to our VPN Routers and has allowed us to share Sabai OS with thousands of new users around the world.

We are, however, still awaiting an update to the VPN Accelerator that extends this capability. So, if you are using a VPN provider that requires a username/password input for Open VPN (Private Internet Access, Surfbouncer, and PureVPN among others) and you want to use a VPN Accelerator, there is some special setup necessary.

Again, username and password is no issue on the VPN routers, it is just not as simple on the VPN Accelerator (want to see how easy it is on the VPN Router? Watch this video.) This setup requires some advanced moves, so please read the entire set of directions and decide that you are comfortable completing the process before beginning.

Username/Password in VPN Accelerator

Log into your Sabai VPN Accelerator.

Navigate to Diagnostics > System.

Create a file with your username and password by copy and pasting the following lines into the box under word “shell.” You will need to change “username” and “password” to reflect your actual username and password. (Note: leave the “/n” in place. See image for example.)

exec 2>&1

echo -e “username\npassword” > /home/dumbroot/myauth.txt


Hit the Execute button.

Verify that the file was written by copying and pasting the following lines of code into the box under the word “shell” and hitting the Execute button.

exec 2>&1

cat /home/dumbroot/myauth.txt

exec 2>&1

Navigate to VPN > OpenVPN and load your Open VPN configuration file. Once the file is loaded, click Edit.

Find the line in the file that says, “auth-user-pass.”

Add the following line of text to the end of that line. (See picture for example.)


Click Save and Start to start the VPN.

These steps will allow you to run a username/password Open VPN configuration on the VPN Accelerator. We recognize that these are advanced steps. If you are not comfortable completing these steps, please feel free to submit a support ticket and our team will happily set this up for you via our hands-on remote in service.


Customer Spotlight Part 2: Yossi, VPN Accelerator

In Part One of Yossi’s Customer Spotlight, we learned how he uses a single Sabai VPN Router to run dual gateways in Israel. Next, we will discuss how Yossi uses a VPN Accelerator to increase the usability of his VPN network.

The addition of a VPN Accelerator to your wireless VPN setup can make or break your ability to watch streaming content, depending on where you live in the world. There are many factors that affect VPN speed and some of them are controllable and some are outside of your control. Here is a short list:

Power of VPN Router

If speed is of major concern to you, order a higher end router like the RT-N66U or the 4200. The more power the router has behind it, the better your speed throughput will be. This is exactly why a VPN Accelerator helps so tremendously.

Add a VPN Accelerator

A VPN Accelerator is a mini computer that handles the VPN part of the network for the router, letting the router focus on directing traffic – it’s intended job! By adding a VPN Accelerator, you can expect the same speeds achieved by running the VPN directly on a computer. If you haven’t tried this, doing a speed test this way is the best way to estimate Accelerator network speeds. Your VPN provider will have directions on its website for using VPN directly on your computer.

Location of your VPN Server

Choose the closest possible VPN server for your needs. If you are in South America, connect to Miami or Santa Fe, not New York. If you are in Japan, connect to San Francisco, not Miami. You get the picture.

Type of Connection

Wired connections are always faster than wireless. If speed on a specific device is critical, for instance your PS3, then connect that device directly into your VPN Router, rather than streaming content wirelessly. This should cause a noticeable difference.

Local Speed

Nothing can increase your local ISP speed. This is one of the factors that is not controllable. Internet speeds are diverse, depending on where you live in the world. Some Asian countries see as much as 100 Mbps while many island nations struggle to get 5 Mbps. Once you add VPN and a VPN Router to your setup, the best we can do is optimize to get as close to your local speed as possible.

VPN Traffic Throttling

If you live in a part of the world that downgrades VPN traffic as “undesirable” there is nothing that you, your VPN, or Sabai can do to overcome that. The only suggestion we can offer is to be sure to try both PPTP and OpenVPN because each works better in some locations than others.

For Yossi, a VPN Accelerator gives him the speed necessary to enjoy Netflix and Hulu Plus content. “I can watch streaming content as well as play streaming content (Pandora, Spotify) whenever I feel like it. It alleviates my dependency on iTunes downloads and makes my Apple TVs a more “complete” device,” comments Yossi.  ”It make me feel (at least from the standpoint of content) as if I live in the US.”

Troubleshoot Tuesday: Will a DD-WRT Router work with a VPN Accelerator?

VPN Accelerator by Sabai TechnologyIn the nine months or so that Sabai Technology has offered the VPN Accelerator, hundreds of the mini computers have been shipped all over the world. For customers who want to get the best possible speed out of their VPN setups, the VPN Accelerator is a must-have.

The VPN Slow Down

Consider this scenario: Let’s say your local internet speed is 20 Mbps in Germany. You want to be able to watch American Netflix, so you add  VPN connection to tunnel your traffic back to New York. Using VPN directly on your computer still gets 16 Mbps, but the problem is you really don’t want to watch Netflix on your computer, you want to watch it on your Smart TV.

So, you get a Sabai VPN Router and run your VPN connection through the router instead of your computer. This allows you to use VPN with your Smart TV and other networked devices in your home. But, even an RT-N66U WiFi VPN Router will slow your connection speed down a bit more, to maybe 12 Mbps – because even the most powerful VPN Router is still not as powerful as a computer. Your wireless VPN speed might still be plenty fast to watch Netflix, but you miss the speeds you used to have!

Overcoming Speed Issues

The answer to overcoming the majority of the speed slowdown is to purchase a VPN Accelerator, which will overcome the bottleneck caused by the VPN Router (it will not overcome limitations placed by your ISP on VPN traffic or make your network faster than your local connection.) Because the VPN connection actually runs on the VPN Accelerator but routes traffic through the Sabai VPN Router, it provides the speed advantages of running a VPN on the computer with the networking advantages of running VPN on a router. The best of both worlds!

Sabai Customer Care is asked all the time whether or not a VPN Accelerator will “help” a certain network setup. The best way to test what kind of speed results can be expected from a VPN Accelerator is to run your VPN directly on a computer and do a speed test. The VPN Accelerator will be able to match or exceed these speeds.


Customers also ask if they can use a VPN Accelerator with a DD-WRT router. The VPN Accelerator was created to work specifically with Sabai OS, so the answer is no. However, if you enjoy your DD-WRT router for VPN, you will love Sabai OS for all its advanced functionality and features. Plus, the setup is incredibly easy compared to DD-WRT.

If you have more questions about Sabai VPN Routers or the VPN Accelerator, contact Sabai Customer Care by e-mail, chat, or phone. Our office hours are Monday-Friday 8  am – 5 pm EST.


Customer Spotlight: Life in Canada with a VPN Accelerator!

Canada is the perfect VPN Accelerator country!

It must be very frustrating for Canadians to live so close to the United States and yet have so much entertainment – movies, music, and television shows – blocked! Because of exactly this issue, many Canadians are turning to VPN accounts and VPN Routers to be able to stream American content to their Apple TV, Roku, Smart TV, and more.

Don is a great example of one of these customers. He is a StrongVPN customer and found Sabai Technology through that service. After reading reviews and comments from users on the Sabai Technology website, Don decided to purchase a VPN Router and VPN Accelerator.

Thanks to my VPN Accelerator, I now can effortlessly stream anything (Vudu HDX, Netflix HD, Amazon Prime HD, and Hulu Plus) through my VPN thanks to the VPN Accelerator. I am now able to stream all media with ease! Support staff is terrific, all problems and questions answered very quickly!

Because of the fast native speeds and proximity to the United States servers, Canadian customers are almost perfect VPN Accelerator candidates. The VPN Accelerator is a small computer that works in conjunction with a VPN Router by Sabai Technology. The purpose of the Accelerator is to take the VPN processing burden off of the VPN Router, since it isn’t very powerful. With a setup like this, a VPN user gets the same kinds of VPN speeds on all of their devices as when they run VPN directly through the computer!

An example setup:

Lets pretend Don gets local internet speeds of 20Mb/s in Canada. He can run VPN directly through his computer and get 12Mb/s while connected to New York. That is perfectly fast enough to stream HD content from American Netflix or Hulu.

But, Don really want to stream that HD content over his Smart TV, so he has to get his TV connected through VPN. This is where the VPN Router comes in. The VPN Router is going to enable Don to put any network device on his VPN account. Anything that connects to the internet in his home can now appear to be in New York. Great!

Except – Don finds out that once he adds the VPN Router to the mix, it slows his connection down to 6 Mb/s. This will still allow him to stream content but it is too slow for HD. By adding the VPN Accelerator to his setup, Don is able to overcome this last slowdown and get his speeds back up to the 12 Mb/s that he gets directly on his computer. Now Don can stream content in HD from America on his television. Even better!

Why does the VPN Router slow down the connection?

VPN Routers are modified consumer grade routers from companies like Cisco or Asus. To put it plainly, these routers are really dumb computers meant to do one thing – route traffic wirelessly to the internet. Sabai Technology adds a lot of extra capability to the router by asking it to connect to the VPN. Because VPN includes encryption and compression it is a lot of work for these simple routers.

The reason your computer is so much faster at processing VPN traffic is because it is much more powerful. Sabai had the idea that if we could couple the VPN Router with a simple, small computer that could do the extra work of the VPN it would speed up the process quite a bit. So, that is what we did. The VPN Accelerator is basically a small computer that works with your VPN Router by Sabai giving you the best possible routing speeds for VPN.

Customer Spotlight: TheBert in Stuttgart!

Before becoming a VPN user, having a home in Stuttgart, Germany meant that for half the year, TheBert couldn’t enjoy the same Netflix Streaming options that he did while at home in Florida. TheBert quickly discovered that a VPN would allow him to enjoy American Netflix from Stuttgart – or anywhere else in the world.

After settling on StrongVPN as a provider, TheBert started searching for ways to share his VPN connection with a Roku, his favorite content streaming device.  It was a StrongVPN’s recommendation of Sabai Technology VPN Routers that originally referred TheBert to the Sabai website, but it was the customer reviews and recommendations from colleagues that convinced him to make a purchase.

Now, TheBert uses both a VPN Router and a VPN Accelerator to get maximum speed output. When asked how big of a difference the VPN Accelerator made to his VPN home network experience, TheBert says, “I have seen a difference when I am streaming video through my Roku box.  While watching  a movie before it would cut out in the middle of the movie and start streaming again.” The Accelerator has greatly diminished these issues.

The Sabai Technology VPN Bundle has given me the ability to really utilize my Roku and enjoy some of the services I have back at my home in Sarasota, Florida. In addition, the customer service is outstanding. On the occasions I have had to call technical support, the responsiveness and technical ability has been outstanding. I can’t wait to see what Sabai adds next. How about the ability to hook my Slingbox account into my Router? Now that would be awesome!

L2TP Supported Via VPN Accelerator

Layer 2 Tunneling Protocol (L2TP) has roots in PPTP but is more reliable and secure. Previous to the VPN Accelerator, Sabai OS did not support L2TP. However, if you have the VPN Accelerator by Sabai OR if you are looking at purchasing the VPNa Bundle, you can enjoy the additional option of L2TP!

So, how does L2TP stack up? See for yourself:


The Sabai team tested incredible speeds in house with L2TP, however, initial results in the field have been disappointing. It is clear that L2TP is not as fast as  OpenVPN. Much of this is caused by the fact that data is encapsulated twice, so it is less efficient. If you try L2TP on your VPN Accelerator, we would love to hear your results. Sabai is actively collecting this data and working to optimize the user experience.


L2TP uses the IPSec protocol which has no major security weaknesses. The VPN Accelerator ensures that the algorithm is secure by asking you to use an additional password (PSK). Overall, if setup correctly, IPSec is considered to be very secure. It should be noted that although L2TP is not as easy to block as PPTP, it is still easier blocked than OpenVPN. Protocol blocking does not compromise security, it simply prevents the traffic from going through.


Even though L2TP is very similar to PPTP, it does not come with many of the reliability issues that plague many PPTP setups. The stability of L2TP is comparable to OpenVPN in most areas.


L2TP’s setup difficulty is somewhere between PPTP and OpenVPN. However, with the VPN Accelerator by Sabia Technology, it is as simple as possible.  The picture below shows how easy the setup is on the VPN Accelerator.

L2TP setup on the VPN Accelerator

For many VPN providers, L2TP is included in your PPTP package making it easy to try out for yourself. For customers who can’t or don’t wish to pay extra for OpenVPN, but want increased security and reliability over PPTP, L2TP may be a reasonable option.

If you think you could benefit from an L2TP setup, or if you just want to give it a shot, start by visiting your VPN providers website, and choosing an L2TP server from your options list. Next, log in to your VPN Accelerator and click the SabaiVPN tab in the menu on the left. Choose L2TP from the drop-down list and input the server, username, password and PSK. PSK stands for Pre-shared Keys and adds an extra layer of encryption to your connection. With this information input, just click Start! Now that you are off and running on L2TP, try a speed test to see how you like this new method of connection through your VPN Accelerator.

Don’t forget to share your speed results in comments!

Troubleshoot Tuesday: Adding to the Mix


The response to the VPN Accelerator has been humbling and exciting for Sabai Technology. It appears that blazing fast VPN routing speeds are much sought after! The reviews have been fantastic, but whenever you mess with an already successful network setup, there are bound to be bumps in the road. For customers who are having trouble getting their devices to switch on Dual Gateway, after setting up the VPN Accelerator, there is a simple solution!

If you recently added the VPN Accelerator to your network and are having trouble getting your network devices to switch from or to the VPN when you switch them in the Dual Gateway page, simply de-activate and then re-activate Dual Gateway. To complete this simple task, click the button at the top left corner of your Dual Gateway page on your Sabai VPN Router network (pictured below). This simple step is easy to overlook, but is a simple fix to a frustrating problem.
