Disabling network access

There are several ways of doing this.

Approach 1: Blocking network access via flatpak-spawn

This works only with the flatpak package

1. Right click your game and press Configure

2. Go to System options

3. Scroll down and add the following as a Command prefix to your game

flatpak-spawn --no-network

Approach 2: Blocking network access via a firewall (Recommended)

This works with all lutris packages

1. Install opensnitch (or a firewall like that) for your distribution (e.g. sudo pacman -S opensnitch)

2. Setup a rule for your runner (For this tutorial we'll be going with ge-proton )

3. Select Reject for the Action

4. Tick the From this executable checkbox and put the path to your runner

5. Set the Duration to Always

6. Click Save

Approach 3: Using the native package with firejail

This only works with native lutris packages

1. Install firejail for your distribution (e.g. sudo pacman -S firejail)

2. Add this firejail --noprofile --net=none as a Command Prefix to your game
