Host Firewall Basics


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 provides a simple graphical user interface for the Uncomplicated Firewall program. [1]

How-to: Install and Configure a Firewall[edit]

The following steps install gufw on a Debian host.

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, users can add special firewall rules, use pre-configured options for common programs and services, or set other advanced options in gufw by following this guide.

For further information on firewalls, see here.

References[edit]

  1. Uncomplicated Firewall by itself only provides a command-line interface for managing the netfilter firewall. Iptables are used by the program for configuration.
  2. The firewall is disabled by default.
