On the Horizon: wg-dynamic

wg-dynamic is a tool designed officially by the WireGuard developing team. This new utility will provide a convenient way of configuring networks dynamically, where mesh network being one of the them. If you're interested, check it out at wg-dynamic@github or wg-dynamic@official repository.

Version 2

Say hello to version 2! This version is a complete rewrite of the pervious versions. Detailed information can be found in the changelog. Please tell me if you like or hate this new design by posting an issue.


wg-meshconf is a tool that will help you to generate peer configuration files for WireGuard mesh networks. You can easily and quickly create WireGuard mesh networks using this tool.


  • Python >= 3.6
  • cryptography
  • rich

Installation (pip)

wg-meshconf is available on PyPI. You can install it with pip and run the program via the wg-meshconf command.

# installing the program with pip
pip3 install --user -U wg-meshconf

# running the program
wg-meshconf showpeers

Installation (Manual)

Alternatively, if you do not want to install the program into the system with pip, you can clone this repository using git or download the master branch's ZIP file.

# cloning the repository with git
git clone https://github.com/k4yt3x/wg-meshconf.git

# download the master branch's ZIP file
wget https://github.com/k4yt3x/wg-meshconf/archive/master.zip

# decompress the ZIP file
unzip wg-meshconf-master.zip

Then, you will need to install Python's dependencies.

# if you cloned this repository
pip3 install --user -Ur wg-meshconf/wg_meshconf/requirements.txt

# if you downloaded and decompressed the zip file
pip3 install --user -Ur wg-meshconf-master/wg_meshconf/requirements.txt

Learn by an Example

Usages are dull and boring. Let's see a real-life example of how this tool can be used. This section will demonstrate how to create a simple mesh network with four nodes using wg-meshconf.

For this example, suppose you have four servers as shown below. These servers can reach each other via the Endpoint address. For instance, server tokyo1 can ping server shanghai1 with the address shanghai1.com.


Step 1: Add Basic Peer Information

You will first need to add the peers' information into the database. There are two ways to do it: via Excel and via the command line interface.

Method A: With Excel

wg-meshconf has changed its database format from JSON to CSV and added the init command since version 2.4.0. This means that it is now possible for users to directly edit the database file with Excel or other CSV-compatible editors to create/read/update/delete peer information.

(P.S. I thought about making a fancy GUI for wg-meshconf like the other tools, but then I thought, why do it the complex way when you can simply "borrow" Excel's GUI?)

Run the following command to initialize a new database file. By default, the database file is named database.csv. You can also specify the file's name via -d.

wg-meshconf init

Open the database CSV file with an editor like Excel or LibreOffice Calc. You should see the following column headers.


You can then fill in the peers' information. You will need to fill in at least the peers' Name, Address, and Endpoint values. These values cannot be automatically generated.


Once you're done, save the file and execute the init command again to automatically generate the rest of the needed information such as peer private keys.

wg-meshconf init

If you check the file again, you'll see the necessary fields getting automatically filed in.


Method B: With Terminal

If, for some reason, you don't want to edit the database file directly, you can also use this tool purely through its command line interface.

First we need to add all peers in the mesh network into the database. The basic syntax for adding new peers is:

wg-meshconf addpeer NAME --address IP_ADDRESS --address IP_ADDRESS_2 --endpoint ENDPOINT
  • New private key will be generated automatically if unspecified
  • ListenPort defaults to 51820 per WireGuard standard
  • All other values are left empty by default

There are more options which you can specify. Use the command wg-meshconf addpeer -h for more details.

After adding all the peers into the database, you can verify that they have all been added correctly via the wg-meshconf showpeers command. The simplify switch here omits all columns with only Nones.


Step 2: Export Configuration Files

Use the genconfig command to generate configuration files for all peers. You may also export configurations for only one peer by specifying the peer's name.

The configuration files will be named after the peers' names. By default, all configuration files are exported into a subdirectory named output. You can change this by specifying output directory using the -o or the --output option.


Step 3: Copy Configuration Files to Peers

Copy each of the configuration files to the corresponding peers.


Step 4: Start WireGuard Services

Start up the WireGuard interfaces using the wg-quick command. It is also possible to control WireGuard interfaces via WireGuard's wg-quick@ systemd service. WireGuard status can be verified via the wg command after WireGuard interfaces are set up.


Step 5: Verify Connectivity

Verify that all endpoints have been configured properly and can connect to each other.


Done. Now a mesh network has been created between the four servers.

Updating Peer Information

If you would like to update a peer's information, use the updatepeer command. The syntax of updatepeer is the same as that of the addpeer command. Instead of adding a new peer, this command overwrites values in existing entries.

In the example below, suppose you would like to update tokyo1's endpoint address and change it to tokyo321.com. Use the updatepeer command and specify the new endpoint to be tokyo321.com. This will overwrite tokyo1's existing Endpoint value.


Show Peer Information

The showpeers command prints all peers' information by default.


Now that's a lot of info and a lot of unnecessary columns which only have Nones. Therefore, I added the -s/--simplify command which omits those useless columns.


You may also query information about a specific peer.


Plaintext mode has a similar usage. It's just a bit harder to read, at least for me.


Deleting Peers

Use the delpeer command to delete peers. The syntax is delpeer PEER_NAME.

This example below shows how to delete the peer tokyo1 from the database.


Database Files

Unlike 1.x.x versions of wg-meshconf, version 2.0.0 does not require the user to save or load profiles. Instead, all add peer, update peer and delete peer operations are file operations. The changes will be saved to the database file immediately. The database file to use can be specified via the -d or the --database option. If no database file is specified, database.csv will be used.

Database files are essentially just CSV files (it was JSON before version 2.4.0). Below is an example.


Detailed Usages

You may refer to the program's help page for usages. Use the -h switch or the --help switch to print the help page.

$ wg-meshconf -h
usage: wg-meshconf [-h] [-d DATABASE] {addpeer,updatepeer,delpeer,showpeers,genconfig} ...

positional arguments:

optional arguments:
  -h, --help            show this help message and exit
  -d DATABASE, --database DATABASE
                        path where the database file is stored (default: database.json)

Specify -h or --help after a command to see this command's usages.

$ wg-meshconf addpeer -h
