Hosting and Connectivity Guide

In Foundry Virtual Tabletop, a game session has one host and several clients. In order to enjoy a multi-player gaming experience the clients must be able to connect to the host which is running the tabletop software.

Hosting Modes

There are two main hosting modes. The following section attempts to help you understand which hosting mode may be the best choice for you.


In a self-hosted setting, the application runs on your own computer and creates a local web server which allows other players to connect directly to your computer. The self-hosted mode is most similar to the setup of Fantasy Grounds, Maptool, or GM Forge.


  • Free (assuming you have a computer).
  • Almost zero setup.
  • Easy management of content using your own computer’s file system.


  • Your world is only available when the host is running a session.
  • Requires clients to be able to connect to your computer - either through a local network or using port forwarding.
  • Player experience depends on the host’s internet speed.


In a dedicated hosting setting, the application runs on a persistent web server using node.js and all players (including the GM) connect to the game session. The dedicated hosting mode is most similar to the experience of Roll20 or Astral.


  • Your world is always online, although gameplay can be paused in between sessions
  • Clients connect to your world regardless of local network configurations.
  • Network transfer speeds are typically faster than self-hosted resulting in a better player experience.


  • Requires a accessible web server which is configured to serve the Foundry VTT application.
  • More complicated initial setup, especially for users who are unfamiliar with web hosting.
  • Your world’s static files (maps, tokens, music) need to be served from a static location or from the web server.

Self-Hosted Configuration

In a self-hosted configuration, you will need to ensure that clients can connect to your PC using your IP address. There are multiple ways to achieve this and you can use a combination of approaches for different players. By default, Foundry Virtual Tabletop runs on port 30000.

1. Local Area Network. If your players are on the same network as you, they should be able to connect to your computer using your local IP address. To discover your own local IP address: for Windows check your Connection Settings or use ipconfig from the Command Prompt, for Mac look at Network Settings under System Preferences or use ipconfig in your Terminal, for Linux use hostname -i. Local network players should connect to your local IP address and port, for example http://x.x.x.x:30000.

2. Port Forwarding. If your players are connecting over the internet, they will use your public IP address. Use a site like to easily discover your public IP address. In order for this to work, you will need to forward web traffic for your local network to send the Foundry VTT port to your computer’s local IP address. This step is required in order for your network to know where to send the connection. Port forwarding can be intimidating for some users, but it is the recommended approach as it is more secure than other options. The exact steps to implement port forwarding will depend on your network configuration and hardware. Most frequently, port forwarding is done within your router configuration interface. The website has general instructions for the most common router configurations. Once the port is forwarded corretly players can connect to your public IP address in the browser http://x.x.x.x:30000.

3. Virtual Private Network. If your players are remote but port forwarding is not an option, a third option can be to use a VPN service. Please be aware - if you find yourself in this situation, the dedicated hosting option may be a better choice for you. With a virtual private network, other users will have access to details about your computer as well as any content (like documents or pictures) that you are sharing with your local network. If you do choose to go down this route, however, services like Hamachi ( can create a virtual network - once inside a VPN your players can connect to your session using the above instructions for Local Area Network.

For self-hosted installation simply download the zipped application which is suitable for your operating system and extract the archive into a directory of your choice.

The first time starting the application under a self-hosted configuration, you may be prompted by your operating system for permission to allow the application to interact with the external network. Be sure to allow this permission otherwise network traffic may be blocked by your operating system firewall.

Dedicated Configuration

The configuration for a dedicated server will vary somewhat depending on your hosting platform and networking requirements. This section provides a simple configuration example for running the server using an AWS free tier t2.micro instance (

1. Launch a t2.micro (or larger) instance using the Linux distribution of your choice. These instructions are for the standard Amazon Linux AMI.

2. Configure the inbound rules for your instance security group using the AWS dashboard to allow inbound traffic using a Custom TPC Rule for port 30000 (or a different port of your choice).

3. Connect to your new host via SSH. You will need to configure your SSH client to use the security key-pair provided by AWS.

  1. Update software versions and install nodejs to host the server.

    For Red Hat / Amazon Linux:

    sudo yum install -y gcc gcc-c++ make openssl-devel
    curl --silent --location | sudo bash -
    sudo yum install -y nodejs

    For Debian / Ubuntu:

    sudo apt install -y build-essential libssl-dev curl
    curl -sL | sudo bash -
    sudo apt install -y nodejs
    For Windows: Download and install node.js from
  2. Download and extract the Foundry Virtual Tabletop version of the platform architecture.

  3. Start the server, being sure to pass the headless flag: node main.js --headless.

7. Once the server is running, both you and your players can connect to the server using the public IP address of your web host, for example http://x.x.x.x:30000.

Command Line Arguments

By default, Foundry VTT uses port 30000. You can modify which port is used by passing the --port=<port> flag at runtime.

You can also specify the name of a world directory that should be automatically loaded when the software starts by passing the --world=<worldname> flag.

Where Do I Put My Content?

Once your server is up and running the first step is to create a new World. Once you have a world created, you will want to start making static content like maps, tokens, audio files, and more available to be used in your world. Your world data is stored in the public/worlds/<your-world> directory. Feel free to use any directory structure you want within the public folder for organizing your content either for a single world or to be shared across multiple worlds.

When referencing file locations within the VTT - all paths are relative to the public folder which is your content root. For example; suppose you create the following file:


When using that map as the source for a new Scene - you should reference the file location as:



Regarding File Naming Conventions: Since Foundry VTT works as a web server, you should be sure to use directory and file names which conform to web file and URL encoding conventions. You should generally avoid using spaces or special characters as these are likely to cause issues when serving your content to other players. See Google URL Guidelines for more detail.
