How to set up a private Mumble voice chat server

Discover how you can host a private Mumble voice chat server on Windows, macOS, and Linux and communicate with your friends over Meshnet.


In the realm of online gaming and collaborative work, clear and reliable vocal communication is crucial. Whether you're strategizing with your teammates during a heated match or collaborating on a joint project, efficient communication can make all the difference.

Mumble is a popular, free, and open-source software tool designed for voice chat that provides high-quality, low-latency communication between users. By hosting your own Mumble server, you can customize your server configuration, manage user permissions, and avoid dependence on cloud-based communication services. However, accepting outside connections to your self-hosted server requires port forwarding, which can greatly reduce the security of your home network.

Meshnet provides you with the technology that can connect remote devices to a single virtual network. This setup allows other devices in your Meshnet to remotely connect to your Mumble server without opening any ports in your firewall.

This article will showcase how you can configure a personal Mumble server on Windows, macOS, and Linux and connect to it from other devices in your Meshnet.

Set up the Mumble server

To begin, you need to install the Mumble server software on the device that will host your server.

Install the Mumble server

To install the Mumble server on Windows:

  1. Download the Windows server (x64) installer file.

  2. Launch the downloaded file.

  3. Follow the instructions provided by the installation wizard.

  4. Click Finish to complete the installation.

Configure your server

To configure and start your Mumble server on Windows:

  1. Open PowerShell.

  2. Execute the following command to create a new Mumble folder with a Murmur subfolder in your Local AppData directory, and then navigate to the Murmur folder.

    mkdir $env:LOCALAPPDATA/Mumble/Murmur; cd $env:LOCALAPPDATA/Mumble/Murmur

  3. Create the murmur.ini server configuration file and open it using Notepad by running this command:

    notepad murmur.ini

  4. Copy the contents of the mumble-server.ini file from Mumble’s GitHub repository and paste it to the Notepad window.

  5. Press Ctrl + S to save changes.

  6. Exit Notepad.

  7. Launch the Mumble server.

Once the server is launched, you should see the Mumble server icon in your system tray.


You can make changes to the murmur.ini configuration file to customize your Mumble server. Learn more about the available options in the configuration file in the Mumble wiki.

Connecting to your Mumble server over Meshnet

With the server up and running, you and your friends can join the Mumble voice chat using Meshnet.

Install the Mumble client

First, you need to install the Mumble client. You can download the Mumble client installer files for Windows and macOS from the Mumble downloads page.

For Linux, execute the following command in the terminal:

sudo apt install mumble -y

Connect to your server

Once the client is installed, take the following steps to connect to your Mumble server:

  1. Launch Mumble.

  2. Follow the instructions provided by the initial setup wizard.

  3. In the upper-right corner, click the “Open the server connection dialog” button.

  4. Select Add new.

  5. In the new pop-up window, fill in the following information:

    • In the Address field, enter the server device’s Nord name or Meshnet IP address. If you are connecting from the same device that is running the Mumble server, enter localhost instead.

    • In the Username field, enter your custom username.

    • In the Label field, enter a custom name for the server. Example

  6. Click OK and Connect.

  7. Select Yes to accept the server certificate.


If you change the port number in the server configuration file, you must also specify the correct port number when connecting to the server.

You should now be connected to your personal Mumble server over Meshnet.
