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
