แนะนำ Open Source Linux Firewall น่าใช้งาน
1. IPFire (www.ipfire.org)
IPFire is a hardened, versatile, state-of-the-art Open Source firewall based on Linux. Its ease of use, high performance in any scenario and extensibility make it usable for everyone.
IPFire is a Linux-based stateful firewall distro that’s built on top of Netfilter. It began as a fork of the IPCop project, but has since been rewritten based on Linux From Scratch. IPFire can be deployed on a wide variety of hardware, including ARM devices such as the Raspberry Pi.
2. OPNsense (www.opnsense.org)
Free & Open source – Everything essential to protect your network and more
OPNSense is derived from the efforts of two mature open source projects, namely pfSense and m0n0wall.
Instead of using Linux, OPNsense is powered by HardenedBSD, which is a security oriented fork of FreeBSD. The firewall distro is designed to serve as a firewall and routing platform and besides filtering traffic can also be used to display a captive portal, shape traffic, detect and prevent intrusions, as well as setup a Virtual Private Network (VPN), and lots more.
In its bid to respond to threats in a timely fashion, the firewall distro offers weekly security updates. One of the best features about OPNsense is that it exposes all its functionalities from inside a web-based interface, which is a pleasure to use and is available in multiple languages.
3. pfSense (www.pfsense.org)
Best free Linux firewall that’s feature-rich and FreeBSD-based
pfSense describes itself as the most trusted open source firewall. The original FreeBSD-based firewall distro, pfSense shares many similarities with OPNsense. For instance, in addition to being a powerful, flexible firewalling and routing platform, it includes a long list of related features. To begin with, just like with OPNsense, you can use pfSense to deploy an intrusion prevention system as well as enable VPN access.
An open-source security solution with a custom kernel based on FreeBSD OS. pfSense is one of the leading network firewalls with a commercial level of features.
4. ClearOS (www.clearos.com)
ClearOS is a CentOS-based distro that’s designed as a full featured replacement to commercial server distros like Red Hat Enterprise Server or Windows Small Business Server.
There are several editions of ClearOS including a community-supported edition that is offered as a no-cost free download. You can use the community edition of ClearOS to roll out all kinds of network services including a firewall, with content filtering and intrusion detection capabilities.
The best thing about ClearOS is its ease of deployment. As most firewall distros are written for the stereotypical geek, it’s nice to see a refreshing change in what seems to have become the de facto standard of ‘cobble it together and think about the interface afterwards’.
5. Endian Firewall Community (www.endian.com/community)
Endian Firewall Community (EFW) is a turn-key Linux based security software product designed for home that can transform any unused hardware appliance into a full-featured Unified Threat Management (UTM) solution.

7. IPCop (www.ipcop.org)
The IPCop Firewall is a Linux firewall distribution. It is geared towards home and SOHO users. The IPCop web-interface is very user-friendly and makes usage easy.
