Do you play a lot of online games, and need a voice chat server for your guild or clan? Do you have more than 8 people that need to be on at a time, for free? Well, provided you have good enough bandwidth (I’d recommend 5 MB or above plans from ISP’s), you can host a Murmur voice chat server. Allowing 100 or more simultaneous connections at once, hosting a Murmur Server is the best free solution you can have without paying a hosting company to host your voice chat server (Generally $8-$10/mo and up depending on your voice server size). Check out our basic Murmur configuration guide below!

Preparing your PC and Network for use with Murmur


Step 1: Prep your OS for use with Mumble/Murmur

You will need to set your computer to a static IP, in order to port forward your router/modem for the voice chat server. To see how to do this: See our How To article!

Step 2: Prep your Network for use with Mumble/Murmur

Next, you will need to configure your network to allow the port for murmur (by default 64738 in TCP and UDP) through to the correct computer. To do this:

Get your router’s IP Address by opening command prompt and running an “ipconfig”, then open your browser to the gateway. Log into the router/modem, and set it to forward port 64738 (Both TCP and UDP) to the internal address of the PC you are installing Murmur on. For a Video Guide, click here

After you have forwarded the port, go to to check if it is open. If it is, proceed to the next step. NOTE: Murmur may have to be open for the port to be seen.

Step 3: Install Murmur on your PC

Now we can install Murmur and set it up. Head over to the download page and install the most recent Windows release here. Start the installation, and when you get to the page where you are asked what to install, select at least the Murmur server. It is recommended to also install Bonjour as well, and Mumble if you plan on using the voice server on the installation PC/Server. After installing Murmur, place a shortcut on your desktop in order to have a quick way to start the server. To do this, go to C:Program FilesMumble (or wherever you installed Murmur to), right click on murmur.exe and click “Create Shortcut.” Rename the shortcut to “Murmur” and drag onto your desktop.

NOTE: Place the shortcut in C:ProgramDataMicrosoftWindowsStart MenuProgramsStartup to have it start automatically.

Set up the Murmur Server

In C:Program FilesMumble (or wherever you installed Mumble to) there is a file called “murmur.ini” that contains all of your Murmur server settings. After making any changes to this file, you must restart your Murmur server for them to take effect. Do this by right clicking the icon in your task bar area, and selecting “Quit Murmur” then re-running the Murmur shortcut you created. It is recommended to at least view/change the following:


None of these fields need to be changed in order for your server to run. “welcometxt” is the text that will welcome people to your server, “port” is to be used if you want to use one other than the default, “bandwidth” is self explanatory, and “users” is the max number of users you will allow onto the server.

It is recommended that you change




with YOURPASSWORDHERE being the password you choose for the server

To have your root channel named to something other than “Root”, uncomment


and change it to

registerName = Tech Raptor Voice Server

but do not change any of the other


lines unless you plan on making the server public. If so, leave serverpassword blank, and adjust


in order to make it public. If you are on a static IP, then registerHostName is optional, but if you are on Cable/DNS, you should not change this field.

Starting Murmur

You can now start Murmur, using either the murmur.exe in C:Programs FilesMumble or the shortcut you created on the desktop.

In order for it to be accessed externally, give users your external address (found at, the port you specified and have forwarded, and the server password. Enjoy Chatting!

Additional Settings and Features to note.

Setting the SuperUser Password

Setting up the SuperUser password is relatively simple. Start out by opening command prompt (Start -> “cmd” -> enter) and entering the following

cd  c:program filesmumble

change the above if that if not where you installed Mumble. After doing so, type

murmur.exe -ini “<path to your ini file>” -supw YOURPASSWORDHERE

putting in the path for the config file under <path>(e.g. “C:Program Files (x86)Mumblemurmur.ini“) and with YOURPASSWORDHERE being the password you have chosen for the SuperUser. Note: This does not start the Murmur server, just sets the password.

Connecting to your Murmur Server with Mumble

Now that Murmur is started, start Mumble. When it is started, click the Add New… button. Then fill the fields with your server’s information.

The Servername field contains the name that will be shown in your server list.

The Address field is the external IP of your server; if you do not know the external IP, go here (from the computer hosting Murmur): NOTE: If using the same PC as the murmur server, just enter your computer’s IP.

The Username field is the user that you want to use (Case Sensitive) If you want to connect as SuperUser, it must be capitalized as such. Since you are going to want to add your user as an admin, put in that username for now.

Registering a user and making it an admin

  1. Join your server following the steps outlined above
  2. When you are connected to the server, right click on your username, and click “Register” – if you do not see this option, ensure that you have an @all ACL that has “Register Self” set to Allow, Applies to sub-channels unchecked.
  3. Reconnect as the SuperUser – Go back to your server list, and on the main Mumble window click Server -> Connect. You will see the server you added in the previous step. Right click it and select “Edit…” Change Username to SuperUser, click OK, then click Connect.
  4. Right click the “Root” Channel (Will be whatever you set it to as in your config file) and click Edit.
  5. Go to the Groups tab
  6. In the drop-down box at the top select the “admin” group
  7. In the “Members” drop-down box at the bottom left, type your username and press enter
  8. Click OK
  9. Follow step 3 to change your username back to the user you added with SuperUser
  10. Connect back to the server
  11. Test your administration ability by right clicking the root channel, clicking Add, and adding a new channel.

Adding Channels

  1. Join your server following the steps outlined above
  2. When you are joined to the server, right-click your “Root” channel and click Add, then add the channel with the name and description (even picture) if you want.
  3. If you want to add sub channels, follow step 2 on the channel you just created.
