PeerGuardian

PeerGuardian is a handy firewall application that helps filter your network traffic using lists of specific hosts. It was made to keep you safe while using P2P, but just a heads-up, it’s no longer being actively developed.

Getting Started with PeerGuardian

When you first open the PeerGuardian app, it will ask you to install a helper tool. After that, you'll need to restart your network application so filtering can kick in.

Managing Your Lists

The main window of PeerGuardian lets you easily manage your lists and even create new ones without any hassle. You’ll decide if you want to allow all ranges or just standard ports, and then add the host list URL or pick a file.

Quick Configuration Toggles

To make things even easier, PeerGuardian allows you to toggle your configuration status quickly. You can also name each list whatever makes sense to you, so identifying them is a breeze!

Monitoring Network Activity

After enabling the host lists filter you choose, PeerGuardian will start blocking certain network connections. You'll see logs of everything happening and can review some cool statistical analysis too!

Understanding Your Data

This app records how many addresses it blocks and shows details on incoming, outgoing, total blocks, and allowed connections. Plus, it turns this info into graphs that update in real-time or at times you select.

Easily Disable Filters When Needed

The best part? If you ever want to disable all filters in PeerGuardian and allow all connections again, it's super easy! However, keeping the protection active while using P2P is really recommended for safety.

A Customizable Firewall Solution

In short, PeerGuardian is a flexible firewall app that works with almost any host list based on what you're doing online. It comes with preset settings for blocking things like ads and spyware but also lets you whip up custom configurations!

A Note on Development Status

Just remember that since PeerGuardian isn’t under active development anymore, the original authors are open to contributions from others who want to help out.
