Whonix-Gateway ™ Firewall Settings[edit]
Modify Whonix-Gateway ™ User Firewall Settings
Note: If no changes have yet been made to Whonix Firewall Settings, then the Whonix User Firewall Settings File /usr/local/etc/whonix_firewall.d/50_user.conf appears empty (because it does not exist). This is expected.
If using Qubes-Whonix ™, complete these steps.
In Whonix-Gateway ™ AppVM. Make sure folder /usr/local/etc/whonix_firewall.d exists.
sudo mkdir -p /usr/local/etc/whonix_firewall.d
Qubes App Launcher (blue/grey "Q") → Whonix-Gateway ™ AppVM (commonly called sys-whonix) → Whonix User Firewall Settings
If using a graphical Whonix-Gateway ™, complete these steps.
Start Menu → Applications → Settings → User Firewall Settings
If using a terminal-only Whonix-Gateway ™, complete these steps.
In Whonix-Gateway ™, open the whonix_firewall configuration file in an editor.
sudoedit /usr/local/etc/whonix_firewall.d/50_user.conf

The file contains an explanatory comment on how to change firewall settings.
## Please use "/etc/whonix_firewall.d/50_user.conf" for your custom configuration, ## which will override the defaults found here. When Whonix is updated, this ## file may be overwritten.
