Host Firewall Basics
From Whonix
Introduction[edit]
It is recommended to use a simple host firewall and deny any incoming connections on all ports. For a Linux host OS like Debian, Ubuntu and Arch Linux, gufw [archive] provides a simple graphical user interface for the Uncomplicated Firewall [archive] program. [1] It is easy to perform common tasks like blocking or allowing P2P, individual, or pre-configured ports.
How-to: Install and Configure a Firewall[edit]
The following steps install gufw on a Debian host [archive].
1. Install gufw.
sudo apt-get update && sudo apt-get install gufw
2. Start gufw.
gufw
3. Press Unlock. Enter the password.
4. Press Enabled. [2]
5. Check the settings.
By default, the settings should be Incoming: Deny and Outgoing: Allow.
Although not recommended, it is possible to add special firewall rules, use pre-configured options for common programs and services, or set other advanced options in gufw by following this guide [archive].
