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.)
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.
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.
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.
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.”
In 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.
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.

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!

The Sabai Technology operating system is famous for the 5-minute setup – practically unheard of for a VPN Router. To prove just how easy this setup is, and for customers who can’t find their original instructions, we have conveniently put them online for download!
You can find these instructions in a few different places:
1. On the side bar of the blog, on the right side, below the Subscribe button.
2. On the Frequently Asked Questions page.
3. Or click on the following links!
If you are still thinking about purchasing a Sabai VPN Router, take a look at how easy this setup is! Get up and running with a secure, foreign IP on all of your network devices in just minutes … these easy to follow instructions should convince you!*Depending on which version of the firmware you are running, the registration process may be slightly different.
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.
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.

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.

2. Better Game Play. Online role player games like World of Warcraft, Age of Conan, The Secret World and even your Xbox Live game play will be smoother and faster without the annoying buffer you may be used to. Game on.
3. Improved VOIP. If you live thousands of miles away from your family and friends, Voice Over IP is your best friend. You probably already know that using VOIP on VPN gives you lower call rates, but the conversation might be a bit choppy on your current VPN network setup. Not anymore. No more robot voice with your VPN Accelerator.
4. More Users. If you share your VPN network with a spouse or kids, you probably get frustrated with limited bandwidth. With the Accelerator managing your VPN network, it is no problem for one of you to stream Netflix while the other is streaming Pandora, downloading, playing games or just surfing the web. More bandwidth = more capacity!
5. Download Faster. Your increased bandwidth with the VPN Accelerator will allow you to upload and download faster than ever before. For instance, an increase from 2 to 10 Mbps could lower the download time of a Gig of information from over an hour to just 15 minutes!
Whatever you are spending your online time doing, the increase in bandwidth that the VPN Accelerator by Sabai would provide is going to make your browsing experience faster and your connection smoother. To see if your setup would benefit from the VPN Accelerator, take our handy speed quiz.

Now that the VPN Accelerator has been in Beta Testing for a while, we have started receiving reviews on user experiences. Read what some of these users have to say about this unique piece of hardware:
Chris from Germany:
For 2 years, I have been a really satisfied customer of Sabai. I use the Asus RT-N16 with a Strong VPN account. Main use is working and surfing in the US with a US IP and watching Netflix – therefore I need a US-IP. I was and am really satisfied with the product and service provided by Sabai.
So when I read on Facebook that Sabai was planning to release a VPN Accelerator, it was my turn to say – “Yes, lets give it a try.” So I took part in the beta program.
The accelerator was delivered to Germany within 2 days. Customs have to be paid.
While unboxing the Accelerator, I discovered that it is a sleek, glossy black little box. The Accelerator is connected by wire to the VPN router. Cable comes with the Accelerator to be connected to the router. Inside the box is a detailed step-by-step instruction aligned with detailed pictures. So I started to work through the instructions. They are very detailed and clear. It took me 5 minutes to get the accelerator up and running. Is it really that simple? Yes, it is.
From now on you still connect to your VPN router but the Accelerator will handle the VPN tunnel. Now on to some speed tests.
Locally I have a 100 Mbit download and 5 Mbit upload cable service. On the VPN router I got 4 Mbit download and 2.5 MBit upload speeds. For Netflix it is okay to watch movies in standard definition - for HD more speed is needed. Now comes the magic: With the Accelerator I get between 12 and 17 Mbit download and 4 Mbit upload speeds. This is 3-4 times the speed I normally get. Now watching Netflix in HD is fun and quick. And, your Sabai team did a really great job. It is so much more fun to surf and watch movies with more speed. Because high speed can only be beaten by higher speeds. And that is what I get with this magic box.
Usually it takes 20-40 seconds till the VPN tunnel gives me the full speed and then it stays at this high speed. To be sure that this is the highest speed, I wrote an email to Ruth from Tech Team and within an hour the managed to connect to my Accelerator and checked all the settings and things. She suggested to switch to OpenVPN for the best speeds and did all the setup for me. That is what I call superb, friendly and lightning fast service.
Wether you call this box pricey or not is your own decision. I, myself, will no longer live without the VPN Accelerator. And the Sabai company personnel is always great.
Keep up the fantastic work – a really satisfied customer from Germany.
Results from testing with StrongVPN OpenVPN are excellent!
My baseline speed without VPN was 31.06 Mbps. Connected to the StrongVPN
server in Miami directly through the E3000 the speed was 6.70 Mbps. Add
in the accelerator and the speed increased to 21.97 Mbps. A gain of 328%.
Another Chris from Germany:
Wow! First off, let me tell you how impressed I am with your customer service and VPN networking products. Being an expat in Germany, your products help my family stay close to home by making it easy to watch our favorite shows, easing the feeling of being homesick. Your products are easy to set up and your service is impeccable. Your technicians are extremely knowledgeable and very polite and courteous.
Next, I want to share how our user experience has changed since installing the Sabai VPN Accelerator. Again, installation was a snap and customer service was as helpful as I have come to expect from your company. From start to finish, it took less than ten minutes to upgrade my VNP router with the latest version of the SabaiOS, configure the VPN Accelerator and dual gateway on the VPN router, and connect all of our devices and computers at accelerated speeds. The speed tests speak for themselves, but the user experience is where we noticed immediate increased performance. With the VPN Accelerator we could watch Netflix from an iPad, download files, connect to my office computer, and stream an HD movie AppleTV with no stopping, pausing, or decrease in performance. What would normally take 30 minutes to buffer in HD was ready in less than 2 minutes.
Here is the data:
•Local Internet Connection: 25Mb/s Down, 2.5Mb/s Up, 13ms ping
•StrongVPN Connection (ONLY): 2Mb/s Down, 2Mb/s Up, 176ms ping
•VPN Accelerator: 15.5Mb/s Down, 2Mb/s Up, 100ms ping
Sabai Technology is so excited about these initial reviews and can’t wait to share more information with you as it becomes available. The VPN Accelerator will be released for purchase very soon – stay tuned!
