Top Four Types of Firewall Software for a Linux Dedicated Server

September 2019

One of the first major decisions you’ll need to make when configuring your dedicated server is which operating system you’ll choose to run. For many, Linux is a great option due to its unrivaled flexibility and customization. Whether you’re looking to set up a powerful gaming server or are seeking the best hosting for your website, Linux can make your life easier.

However, as with any operating system, there are some measures you’ll want to take to keep your data safe. Specifically, you’ll want to make sure you have a Linux firewall set up right away.

Why Do You Need a Linux Firewall?

Having a firewall for Linux servers is important for a number of reasons. The right firewall will provide added opportunity for customization of your server. Specifically, you can use a Linux network firewall to help regulate incoming and outgoing traffic. The best Linux firewalls will also allow legitimate connections between internal and external networks.

Top Four Linux Firewall Options to Consider

If you’ve recently begun your search for a Linux-based firewall, the first thing you probably noticed is how many options are available. You may be feeling a little overwhelmed in choosing the one that’s right for your needs. Fortunately, you can narrow down your options and make your decision easier by considering four of the best Linux firewalls described below.

1. IPCop

If you’re new to the world of Linux and Linux firewalls, then you’re going to want one that’s intuitive and user-friendly. These characteristics are exactly what make IPCop one of the most popular choices for Linux server firewalls. Like Linux itself, this firewall is open-source in its creation and can also double as a secure VPN. If this is your first time using a Linux server, IPCop is highly recommended if you’re looking to keep things as simple as possible.

2. Iptables

Iptables is one of the most popular Linux firewalls out there – and for good reason. Not only does it offer a simple and easy-to-use interface, but policy chains make it simple to regulate incoming and outgoing traffic on your server. This is a great way to add security to your server in a way that’s 100% customizable. When compared to the IPCop interface, many users find the Iptables design to be more intuitive.

3. Shorewall

If your firewall and security needs tend to change frequently, Shorewall may be your best bet. Interestingly enough, the Shorewall firewall itself is based on Iptables. However, the design makes it easier to make changes and offers more customization. On the other hand, its interface is not as user-friendly for Linux beginners, so this may not be the best firewall choice for you if you’re just getting started.

4. Uncomplicated Firewall (UFW)

The name says it all. UFW was designed for beginners, making it easy to configure and make changes as needed. The most important thing to keep in mind if you’re considering using UFW as a firewall is that it’s designed exclusively for use on Ubunto and Debian systems – so depending on the version of Linux you’re using, it may or may not be right for you.
As you can see, there is no shortage of options available if you’re looking for firewall software for Linux. The key is choosing a firewall that will suit your level of comfort and experience. From there, you can operate your Linux server with an added sense of confidence, security, and peace of mind.
