Plug-and-Play VPN router and unblocker


Unzoner is a subscription-based service, designed specifically for Internet content un-blocking. Together, they un-block video streaming content across tablets, smartphones, desktops, laptops and TVs over Wi-Fi or LAN. Unzoner subscriptions can also be created manually for use with compatible software, such as Tunnelblick and Kodi.
TL;DR find a Raspbery Pi and flash it with this image or try this on a PC or router

instructions

Due to a PayPal limitation, subscriptions are not available in Germany (and China), please use Bitcoin instead or find a way to create PayPal accounts in other region(s).
  1. obtain a Rasberry Pi 3 starter kit, download and uncompress the .img file, burn it to a fast 4GB+ SD card with Etcher[n3], then insert the card into the Pi
  2. connect the Pi to the Internet using a spare Ethernet port on your router[n6] and a 2.5A+ power supply[n2]
  3. after initial initialisation of around 10-20 minutes depending on your bandwidth[n5] and SD card speed[n10], visit http://blackbox.local/ or http://blackbox-2.local/ URL
  4. click subscribe (if un-blocking) to setup up a PayPal billing agreement[n11] and claim your 1 month free trial or PAYG using Bitcoin[n7]
  5. once subscribed, you will be redirected back to the dash where you can monitor the status of the device
  6. configure services you'd like to unblock or disable policy routing and configure exceptions
  7. when the dash lights up green, connect to a new Wi-Fi network called black.box (passphrase: blackbox) or set your default gateway to the black.box LAN IP (LAN mode) as shown on the dash
  8. now try accessing some previously blocked Internet content[n9]
  9. for issues, please email support, IRC channel #netflix-proxy on Freenode, or use the live chat link on the dash
  10. to be advised when important stuff happens, subscribe to push notifications on the dash

about

black.box devices operate in three distinct modes. Devices connected to the black.box Wi-Fi network or routed via the device's Ethernet (LAN) IP address, can (a) typically access popular streaming services from anywhere in the world; (b) to provide privacy and anonymity via 3rd party VPN providers; or (c) etablish private VPN links between two or more locations. Application source code is available at https://github.com/ab77/black.box/tree/master/src under the MIT license.

unblocking mode (default)

In the default un-blocking mode, coupled with an active unzoner subscription, black.box device allows access to popular streaming services in the target region from anywhere in the world. In this mode, the device additionally supports obfuscation/cloaking, in order to function in hostile deep packet inspection (DPI) environments, as well as experimental WAN acceleration mode.
PayPal subscription or Bitcoin credit is required to create a subscription. Subscriptions are priced at €9.95 per month, with initial 1 month free (if paid by PayPal). PayPal subscriptions can be cancelled at any time.
Alternatively, pay up-front using Bitcoin for as much time as you need. Price quoted based on EUR/BTC exchange rate. Top-up at any point prior to the existing Bitcoin credit expiry, or after. Any unused Bitcoin credit will be rolled over if topping up prior to existing credit expiry. Topping up after credit expiry will strike a new exchange rate.
For performance reasons, un-blocking traffic is not encrypted[n4]. When policy routing is enabled (default), all traffic goes out via the local Internet interface, except for selected services. When disabled, all traffic is sent via the tunnel, except for selected services. For security reasons, the tunnel interface may be restricted to only allow specific network ports[n1] for streaming, while the local interface is always unrestricted.

VPN mode

In VPN mode, the device supports a number of popular VPN services, such as VPNArea and Private Internet Access. Separate subscriptions/accounts required to access supported VPN services.

server (pairing) mode

In the server pairing mode, multiple devices can be used to establish private encrypted links. Leave one at home/office and dial back in securely when travelling or on holidays to access the Internet via the device in server mode. Unzoner subscription is currently not required in this mode. LAN(s) behind server devices are not accessible (WAN only).

dashboard

Once the device is running, the dash is accessible by navigating to http://blackbox.local/ while connected to the black.box Wi-Fi network or from the LAN. Please do not share your device GUID(s) (the long alpa-numeric string you see in the dash URL) as they are effectively credentials for anyone to access your devices settings and modify them. So, keep them secret.
A live demo dashboard is available here.
black.box dashboard
If multiple regions are available to un-block, click a country flag in the top right corner of the dash. The device will re-boot with the new settings and un-block the selected country.

services

A number of popular services can be selected on the dash. If the service you require is missing please, email support, IRC channel #netflix-proxy on Freenode or use the live chat link on the dash to request it. Also, disabling Policy Routing (optionally disabling Local DNS) as well as setting all Services to none will make unknown services work.

cancellation

Please visit PayPal to cancel your black.box subscription.

QEMU or VirtualBox

If you don't have a compatible device, or waiting for one to arrive, you can use your PC with QEMU or Oracle VirtualBox to run black.box.
You can always configure compatible software on your PC, such as Tunnelblick for use with Unzoner without advanced features, such as policy based routing.

technical architecture

black.box appliances can functions in a number of modes. In the default un-blocking mode, the device automatically connects to the least busy black.box exit-node in the target region and routes traffic through the tunnel, while advertising a local Wi-Fi AP to all consumer devices within range.
In server mode, the device advertises its private GUID and listens for incoming VPN connections from paired device(s). Device(s) in paired mode, which have specified the private GUID in their configuration, locate and connect to the server node, while advertising a local Wi-Fi AP to all consumer devices within range. This mode is useful for establishing point to point links betwen two of more locations.
In VPN mode, the device supports connecting to a number of popular VPN services, such as PIA, VPNArea and VanishedVPN. Additional VPN providers can be easily integrated.
There are two more system modes the device can function in, namely exit-node and double-vpn. These are suitable for white-labelling of the black.box service and are not available via the dash. In exit-node mode, black.box devices advertise themselves to devices running in un-blocking mode. This mode is useful for deploying black.box exit-nodes anywhere in the world with an Internet connection and a power socket. In double-vpn mode, devices both listen for incoming VPN client connections, as well as establish a outbound connection to a down-stream VPN server.
black.box devices run on ResinOS, using resin.io management back-end. OpenVPN 2.4 is used for building black.box VPN tunnels, whether encrypted or otherwise. OpenSSL is compiled with NEON support to accelerate certain cryptographic functions on the ARMv7 CPUs and linked with OpenVPN. Stunnel and WANProxy are use for obfuscation and/or acceleration. You can expect to get anywhere from 5Mbit/s to 10Mbit/s through the Pi Ethernet interface in unblocking mode and less in VPN mode. VPN providers which use default SHA1 authentication should be a little faster, due to ARMv7 NEON optimisations.
Python 2.7 is used for the main application, together with Linux Bash shell scripts to help interface with the operating system. All Python code is compiled into executables using Nuitka on dynamically provisioned Digital Ocean Droplets for both armv7l (QEMU) and x86_64 architectures and shipped to devices in a secure manner, by first encrypting the payload using OpenSSL. Devices are managed using resin.io IoT infrastructure, which runs the black.box code inside Docker containers on custom ResinOS images. All runtime code is unpacked onto encrypted disk partitions inside Docker containers with all transient data stored in memory only and disk encryption keys never recorded.
Amazon AWS (EBS) is used to host both the black.box API (demo) and the device dashboard (demo), which are implemented in Python-Flask and Bootstrap. Amazon RDS is used for transient data storage, persisting for no longer than one hour, and Redis is used for caching.
For subscriptions, the black.box API talks to the PayPal Subscriptions API to set-up monthly subscriptions. For Bitcoin payments, the BlockCypher API provides nesessary WebHooks to advise the black.box API when a payment has been received as well as a WebSocket notification for the dashboard. No Bitcoin payment provider (middle-man) is used in the Bitcoin payment flow.
Additional management VPS is used to provide ipinfo support services as well as execute automated headless video playback tests using Selenium WebDriver wrapped in Python.

footnotes

  1. default ports: 80/tcp, 443/tcp and 53/udp
  2. The radio in the Pi is weak, please try to locate as close as possible to the streaming device(s) or turn the radio off and use in LAN router mode.
  3. Raspberry Pi 2 Model B with an Alfa Network AWUS036NEH USB Wi-Fi dongle will also work and may even provide better signal due to the external Wi-Fi antenna.
  4. For performance reasons, the tunnel interface provides no additional packet encryption/authentication overheads.
  5. The initial application image is currently around 600MB. Subsequent updates are a fraction of that. Monitor by pinging blackbox.local from your LAN. If you have multiple black.box devices on your LAN, the second device will be called blackbox-2.local, the third blackbox-3.local and so on. Maximum 5 devices supported.
  6. For the paranoid, you can locate the device in your DMZ and restrict access to your LAN, however the device needs unrestricted oubound access to the Internet. Your DMZ should also forward mDNS (avahi-daemon) broadcast packets to your LAN for discovery/dashboard access. The device communicates with a private API at AWS over HTTPS and a number of OpenVPN endpoints to enable functionality.
  7. The dash will automatically refresh after Bitcoin payment has been confirmed. This could take a number of minutes, depending on the Bitcoin network load.
  8. Supported devices currently include DD-WRT routers, Kodi, Intel NUC. If you own a supported board, request an image.
  9. Try disabling both Policy Routing and Local DNS on the dash if you are having issues with a particular service. If you have router(s) on your network assigning IPv6 addresses, some IPv6 enabled services may not work (i.e. Netflix). Try disabling IPv6 on your network if this is the case.
  10. Not all SD cards are created equal, see microSD Card Benchmarks and get a fast one. Don't get a cheap SD card since even if you get the device up and running initially, it will be very slow and will fail catastrophically shortly after.
  11. Subscriptions require PayPal support for recurring payments in the country where the buyer account is located (excludes Germany and Austria).
