black.box
is a VPN policy routing appliance, which runs on Raspberry Pi(s),
DD-WRT routers and other[n8] devices.
Unzoner
is a subscription-based service, which helps connect black.box(es)
with
exit-nodes in target geographical regions.

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
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 β¬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.
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 balenaOS, using Balena management back-end.
OpenVPN 2.5.x is used for building black.box
VPN tunnels, whether encrypted or otherwise.
On ARM platforms, OpenSSL is compiled with available optimisations to accelerate certain
cryptographic functions. OpenVPN is linked with optimised SSL libraries. Stunnel and
WANProxy are (optionally) used for obfuscation and/or acceleration. You can expect to get
anywhere from 5Mbit/s upwards 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 on ARM platforms due to complier optimisations.
Python 3.9 is used for the main application, together with Linux Bash shell scripts to
help interface with the operating system. All Python code is (optionally) compiled into
executables using Nuitka and encrypted using OpenSSL. All devices are managed using
Balena
IoT infrastructure, which runs the black.box
code inside Docker (balena-engine)
containers on balenaOS. All runtime code is unpacked onto encrypted disk partitions inside
containers with all transient data stored in memory and with encryption keys never stored
in the images.
Amazon AWS (EBS) is used to host both the black.box
(private) API and the device dashboard,
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. If you
would like to white-label Unzoner, please get in touch.
For subscriptions, the black.box
API talks to the PayPal Subscriptions API to set-up
monthly subscriptions. For Bitcoin payments, the BlockCypher API provides necessary
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.

-
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.
-
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.
-
For performance reasons, the tunnel interface provides no additional packet encryption/authentication overheads.
-
The initial application image is currently around 2GB. Subsequent deltas are small. Monitor by pinging
blackbox.local
from your LAN. If you have multipleblack.box
devices on your LAN/WLAN, the second device will be calledblackbox-2.local
, the thirdblackbox-3.local
and so on. -
For additional security, 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.
-
The dash will automatically refresh after Bitcoin payment has been confirmed. This could take a number of minutes, depending on the Bitcoin network load.
-
Supported devices currently include DD-WRT routers, Kodi and Intel NUC. If you own a supported board, request an image.
-
Try disabling both
Policy Routing
andLocal 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. -
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.
-
Subscriptions require PayPal support for recurring payments in the country where the buyer account is located (excludes Germany and Austria).
