NeT Firewall

NeT Firewall is a powerful firewall app that’s designed to keep your system safe from all sorts of online threats. It’s packed with tons of settings to enhance your operating system's protection. Whether you want to set it up as a personal firewall or a server firewall, it’s perfect for tech-savvy users, like network admins.

User-Friendly Interface

The app comes with a sleek and user-friendly interface. The main window is spacious and well-organized, letting you easily navigate through all the main features using a tree view. You can check out everything from network interfaces and traffic capabilities to security rules and active connections. Plus, you can even minimize the main window to the systray for easy access!

Network Information

With NeT Firewall, you can see all the details about your network interfaces, like their MAC and IP addresses, MTU, and speed. You have the freedom to adjust security levels for each adapter too. Want to look at traffic history? No problem! You’ll get insights into incoming and outgoing packets as well as maximum rates.

Traffic Control

You can also set up different IP address sets for internal and external traffic on your local area network. This helps in controlling network traffic so you can optimize performance while keeping latency low. Plus, you can tweak the IP routing table to manage how traffic flows directly.

Security Rules Management

Creating security rules is straightforward! Just fill in details like rule descriptions, IDs (to prioritize), interfaces, rule types (allow or deny), control directions (incoming or outgoing), and protocols (choose from a list or customize). Don't forget to specify source and destination IP addresses along with ports!

Active Connections Insights

You can investigate TCP and UDP connections currently running on your system too! This includes looking at process names, protocols used, local & remote IP addresses along with port numbers.

Easily Manage Your Connections

If needed, refreshing this list is easy! You can terminate selected processes or create new firewall rules for certain connections. The packet log will show you all sorts of details about incoming or outgoing connections including reasons behind them!

Simplified Data Handling

The software allows you to save important info about your network interfaces, traffic abilities, security rules etc., into files like TXT or CSV format.

Customization Options

You have options here too! Add or remove display columns as needed, hide various menus if they clutter your view, save rules in .rul format for later use, and much more! You can even set NeT Firewall to start automatically with Windows!

Performance Impact

This tool barely affects computer performance during our tests—it made changes instantly without any freezes or crashes. While its interface might seem basic at first glance, it offers essential options for users who know what they're doing. Just wish it had some updates recently!
