eBlocker: Do It Yourself

Selbstbau eBlocker
DIY eBlocker

Making eBlocker yourself is very simple. All you need are a few components, which you can buy “everywhere” for about $50. Everything else you can find here: Completely free, thanks to a great community.

As soon as you got everything together, your eBlocker is ready to go in a few minutes. Instantly you start surfing anonymously and are protected on all devices.

What you need

  1. A Raspberry Pi or Banana Pi M2+ (a mini computer)
    Recommended buy: Raspberry Pi 4 with 2GB RAM
  2. Suitable SD card (min. 8Gb, Class 10)
  3. Suitable power supply unit (min. 3A, otherwise you might get issues)
  4. LAN-Cable
  5. Free LAN port in your router or switch
  6. PC/Mac with SD card reader
  7. The following instructions (please follow carefully)


1. Free eBlockerOS Download

Here you can always find the latest eBlockerOS images for free download.

Do you still use eBlockerOS 2.4 on your device?
Then you can find instructions for upgrading to eBlockerOS 2.5 here.

If you own a “white cube” eBlocker or already use eBlockerOS 2.5.x (also beta), the downloads are not relevant. Your device can be updated to the latest version via the user interface (Settings>License & Update).

eBlockerOS Images

If you find bugs, please share via the forum only. Thanks!

2. Install eBlockerOS on SD Card

The software images must be installed on an SD card with an easy-to-use program like Etcher. Etcher is free to download for Windows, MacOS and Linux.

Note: The image cannot simply be copied to the SD card using Windows Explorer, but must rather be installed. For the installation with Etcher the image does not need to be unpacked.

3. Connect Raspi to Network

Install the prepared SD card in your Raspberry Pi. First connect the Raspi to a free LAN port of your Internet router or switch using the LAN cable.

Please do not connect a monitor or keyboard!

Let’s go: Turn on your Raspi and hook it up to the power.

Wait at least 5 minutes until eBlockerOS has started up and configured itself. Depending on the Raspi model used and the number of network devices, the first start may take some time. Please stay patient 😉


Make sure you’re using a separate power supply with at least 10 watts or 2A (15 watts / 3A for Raspberry Pi 4). Most standard USB ports on computers or routers do not have enough power and can cause sporadic errors.

4. Network Configuration


If you have an Apple iOS device, we recommend to use our eBlocker iOS App for the initial configuration: It will automatically find the eBlocker in your network and the following URL will be called in Safari.

Alternatively use any browser with http://setup.eblocker.com (not https). If everything works, the eBlocker icon automatically appears in the upper right corner of the screen.

You can see that the eBlockerOS is active and protects you. With a click on the icon the eBlockerOS Controlbar opens and allows you to further configure and access your control center. You can find your personal eBlocker Dashboard at http://eblocker.box, as soon as the eBlocker is active.

5. Enter License Key

With the following (in eOS 2.5 already prefilled) license key you can activate your eBlocker for free and permanently for all features:


License key for eBlockerOS without restrictions

You will receive free daily updates for your eBlocker as long as sufficient donations for the operation and maintenance are made. With the previous donations we have already licensed commercial filters (from Malware Patrol, among others) and thus offer the same scope of protection as the formerly commercial eBlocker.

6. Getting Started

First of all get familiar with the basic eBlocker functions, the dashboard and the settings. It is recommended to first enable HTTPS in eBlocker and install the eBlocker certificate on the clients. Then you should mark the trustworthy apps, otherwise you may experience problems with certain apps. In the eBlocker Instant Help you will find all important information.

The initial configuration may take a while: But it’s worth it 🙂

7. Support and Technical Issues

Here you find all help information collected. If you can’t find an answer there, feel free to ask your questions in our forum, where experienced users help others.

Unfortunately we can not offer individual support by email or phone.

We need your Engagement.

Our project needs your help. We would be very happy if you would like to support eBlocker with donations or volunteer with us.
With your help, we can keep eBlocker free and safe for everyone.
