Welcome to the VPN Setup GUI project. This is a Free and Open Source Software (FOSS) project aimed at helping small VPN operators set up their networks quickly and easily.

Setting up a VPN can be a complex task, especially for small operators who may not have a dedicated IT team. This project aims to simplify that process by providing a graphical user interface (GUI) for setting up VPN networks.

With this tool, operators can configure their VPN networks without needing to understand complex networking concepts or write configuration files by hand. The GUI provides a simple, intuitive interface that guides operators through the setup process step by step.

We welcome contributions from the community. If you're interested in contributing, please see our CONTRIBUTING.md file for more information.

At present, the development roadmap is here ROADMAP.md

At present, simply clone this repository onto a Linux machine. A Debian-based linux build is the only currently supported OS.

git clone https://github.com/radawson/wireguard-gui

After the repository is cloned, change directory into the wireguard-gui directory

cd wireguard-gui

Next, install the python requirements with sudo to make them global. Yes, you will get a warning about this.

sudo pip install -r requirements.txt

Once the installation is complete, change directory into src.

cd src

Next, Make any adjustments you need to make to config.yaml. Note that the default IP address is localhost, 127.0.0.1. If you want to access the web interface remotely, change this to an appropriate IP address.

Security warning You can also use 0.0.0.0 to listen on all IP addresses, but understand the implications of this.

The one key in config.yaml you MUST change is the SUDO_PASSWORD. This must be the sudo password for the user that will be running the python script. We DO NOT recommend running the entire python web server with sudo. Your user that runs the wepython script will have to have sudo permission to set up the WireGuard services. If you are only using the datbase for tracking, you won't have tyo use sudo or a sudo user because you won't be elevating permissions.

SUDO_PASSWORD: 'changeme'

The MODE key in the config file determines whether this server will run as a wireguard server (hub) or as a database for configuration files. The options for this key are 'server' or 'database'

This is also a good time to make sure that your firewall has port 5000 (default) open for the webserver. You will also need to open port 51820 UDP (default) for the WireGuard service.

Examples using ufw:

sudo ufw allow 5000/tcp
sudo ufw allow 51820/udp

Pure Python reimplementation of wireguard-tools with an aim to provide easily reusable library functions to handle reading and writing of WireGuard® configuration files as well as interacting with WireGuard devices, both in-kernel through the Netlink API and userspace implementations through the cross-platform UAPI API.

    pipx install wireguard-tools
    wg-py --help

Implemented wg command line functionality,

• show - Show configuration and device information
• showconf - Dump current device configuration
• set - Change current configuration, add/remove/change peers
• setconf - Apply configuration to device
• addconf - Append configuration to device
• syncconf - Synchronizes configuration with device
• genkey, genpsk, pubkey - Key generation

Also includes some wg-quick functions,

• up, down - Create and configure WireGuard device and interface
• save - Dump device and interface configuration
• strip - Filter wg-quick settings from configuration

Needs root (sudo) access to query and configure the WireGuard devices through netlink. But root doesn't know about the currently active virtualenv, you may have to pass the full path to the script in the virtualenv, or use python3 -m wireguard_tools

    sudo `which wg-py` showconf <interface>
    sudo /path/to/venv/python3 -m wireguard_tools showconf <interface>

The WireguardKey class will parse base64-encoded keys, the default base64 encoded string, but also an urlsafe base64 encoded variant. It also exposes both private key generating and public key deriving functions. Be sure to pass any base64 or hex encoded keys as 'str' and not 'bytes', otherwise it will assume the key was already decoded to its raw form.

from wireguard_tools import WireguardKey

private_key = WireguardKey.generate()
public_key = private_key.public_key()

# print base64 encoded key
print(public_key)

# print urlsafe encoded key
print(public_key.urlsafe)

# print hexadecimal encoded key
print(public_key.hex())

The WireGuard configuration file is similar to, but not quite, the INI format because it has duplicate keys for both section names (i.e. [Peer]) as well as configuration keys within a section. According to the format description, AllowedIPs, Address, and DNS configuration keys 'may be specified multiple times'.

from wireguard_tools import WireguardConfig

with open("wg0.conf") as fh:
    config = WireguardConfig.from_wgconfig(fh)

Also supported are the "Friendly Tags" comments as introduced by prometheus-wireguard-exporter, where a [Peer] section can contain comments which add a user friendly description and/or additional attributes.

[Peer]
# friendly_name = Peer description for end users
# friendly_json = {"flat"="json", "dictionary"=1, "attribute"=2}
...

These will show up as additional friendly_name and friendly_json attributes on the WireguardPeer object.

We can also serialize and deserialize from a simple dict-based format which uses only basic JSON datatypes and, as such, can be used to convert to various formats (i.e. json, yaml, toml, pickle) either to disk or to pass over a network.

from wireguard_tools import WireguardConfig
from pprint import pprint

dict_config = dict(
    private_key="...",
    peers=[
        dict(
            public_key="...",
            preshared_key=None,
            endpoint_host="remote_host",
            endpoint_port=5120,
            persistent_keepalive=30,
            allowed_ips=["0.0.0.0/0"],
            friendly_name="Awesome Peer",
        ),
    ],
)
config = WireguardConfig.from_dict(dict_config)

dict_config = config.asdict()
pprint(dict_config)

Finally, there is a to_qrcode function that returns a segno.QRCode object which contains the configuration. This can be printed and scanned with the wireguard-android application. Careful with these because the QRcode exposes an easily captured copy of the private key as part of the configuration file. It is convenient, but definitely not secure.

from wireguard_tools import WireguardConfig
from pprint import pprint

dict_config = dict(
    private_key="...",
    peers=[
        dict(
            public_key="...",
            preshared_key=None,
            endpoint_host="remote_host",
            endpoint_port=5120,
            persistent_keepalive=30,
            allowed_ips=["0.0.0.0/0"],
        ),
    ],
)
config = WireguardConfig.from_dict(dict_config)

qr = config.to_qrcode()
qr.save("wgconfig.png")
qr.terminal(compact=True)

from wireguard_tools import WireguardDevice

ifnames = [device.interface for device in WireguardDevice.list()]

device = WireguardDevice.get("wg0")

wgconfig = device.get_config()

device.set_config(wgconfig)

The setconf/syncconf implementation is not quite correct. They currently use the same underlying set of operations but netlink-api's set_config implementation actually does something closer to syncconf, while the uapi-api implementation matches setconf.

This implementation has only been tested on Linux where we've only actively used a subset of the available functionality, i.e. the common scenario is configuring an interface only once with just a single peer.
