Wiretrustee

A WireGuard®-based mesh network that connects your devices into a single private network.

Why using Wiretrustee?

• Connect multiple devices to each other via a secure peer-to-peer Wireguard VPN tunnel. At home, the office, or anywhere else.
• No need to open ports and expose public IPs on the device.
• Automatically reconnects in case of network failures or switches.
• Automatic NAT traversal.
• Relay server fallback in case of an unsuccessful peer-to-peer connection.
• Private key never leaves your device.
• Works on ARM devices (e.g. Raspberry Pi).

A bit on Wiretrustee internals

• Wiretrustee uses WebRTC ICE implemented in pion/ice library to discover connection candidates when establishing a peer-to-peer connection between devices.
• A connection session negotiation between peers is achieved with the Wiretrustee Signalling server signal
• Contents of the messages sent between peers through the signalling server are encrypted with Wireguard keys, making it impossible to inspect them. The routing of the messages on a Signalling server is based on public Wireguard keys.
• Occasionally, the NAT-traversal is unsuccessful due to strict NATs (e.g. mobile carrier grade NAT). For that matter, there is support for a relay server fallback (TURN). So in case, the (NAT-traversal is unsuccessful???), a secure Wireguard tunnel is established via TURN server. Coturn is the one that has been successfully used for STUN and TURN in Wiretrustee setups.

What Wiretrustee is not doing:

• Wireguard key management. In consequence, you need to generate peer keys and specify them on Wiretrustee initialization step.
• Peer address management. You have to specify a unique peer local address (e.g. 10.30.30.1/24) when configuring Wiretrustee The peer address management assignment is on our roadmap.

Client Installation

1. Checkout Wiretrustee releases
2. Download the latest release:

wget https://github.com/wiretrustee/wiretrustee/releases/download/v0.0.4/wiretrustee_0.0.4_linux_amd64.rpm

3. Install the package

sudo dpkg -i wiretrustee_0.0.4_linux_amd64.deb

Client Configuration

1. Initialize Wiretrustee:

sudo wiretrustee init \
 --stunURLs stun:stun.wiretrustee.com:3468,stun:stun.l.google.com:19302 \
 --turnURLs <TURN User>:<TURN password>@turn:stun.wiretrustee.com:3468  \
 --signalAddr signal.wiretrustee.com:10000  \
 --wgLocalAddr 10.30.30.1/24  \
 --log-level info

It is important to mention that the wgLocalAddr parameter has to be unique across your network. E.g. if you have Peer A with wgLocalAddr=10.30.30.1/24 then another Peer B can have wgLocalAddr=10.30.30.2/24

If for some reason, you already have a generated Wireguard key, you can specify it with the --wgKey parameter. If not specified, then a new one will be generated, and its corresponding public key will be output to the log. A new config will be generated and stored under /etc/wiretrustee/config.json

2. Add a peer to connect to.

sudo wiretrustee add-peer --allowedIPs 10.30.30.2/32 --key '<REMOTE PEER WIREUARD PUBLIC KEY>'

3. Restart Wiretrustee to reload changes

sudo systemctl restart wiretrustee.service
sudo systemctl status wiretrustee.service 

Running the Signal service

We have packed the signal into docker images. You can pull the images from the Github registry and execute it with the following commands:

docker pull ghcr.io/wiretrustee/wiretrustee:signal-latest
docker run -d --name wiretrustee-signal -p 10000:10000 ghcr.io/wiretrustee/wiretrustee:signal-latest

The default log-level is set to INFO, if you need you can change it using by updating the docker cmd as followed:

docker run -d --name wiretrustee-signal -p 10000:10000 ghcr.io/wiretrustee/wiretrustee:signal-latest --log-level DEBUG

Roadmap

• Android app
• The peer address management assignment is on our roadmap.
