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.

Introduction

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.
