pfSense / OPNsense is becoming the most popular FreeBSD based firewall. Some of its features are:

– Firewall to secure your network
– NAT – forwarding TCP ports for Servers, CCTV DVRs, Remote access.
– Multi-WAN Load balancing to use multiple ISPs at the same time (either in failover or load balancing mode)
– VPN – Securely accessing your office network or connecting satellite offices to the HQ
– Reporting – RRD Graphs and real-time traffic graphs
– Dynamic DNS – If you don’t have a static IP, but need to configure VPN or port forwarding for CCTV, you can integrate pfSense with many popular dynamic DNS providers. Like no-ip or dyndns
– Captive Portal – This feature allows you to force authentication, or redirection to a click through page for network access. This is commonly used on Wi-Fi hotspot networks (malls, coffee shops, hotels, airports)

pfSense / OPNsense feature-set can be extended by the use of packages

Comparison with commercial firewalls

Open-Source vs Commercial Firewalls :

Benefits with an open-source firewall are:

– No subscription charges – With most commercial firewalls you have to pay an expensive “subscription fees” to use even the most basic functions. With open-source firewalls, there are no subscription charges whatsoever.

– Lifetime free updates and upgrades – You get free security updates and upgrades to new versions free of charge.

– No user limit – You have no hard limits on number of users. You can add as many users as the hardware resources permit

– Open hardware – If you don’t like pfSense / OPNsense or want to switch to something else, you can easily install virtually ANY operating system without any problems. Once you purchase the hardware, it is yours to do as you like!

– Extensible – You can extend the features of the firewall by installing additional packages of your choice. (Like snort / suricata, squid /squidguard )

– Highly affordable – Most commercial firewalls with 8GB ram (that virtually support 8 Million concurrent connections or more) start at a very high price


Comparison with assembled desktop firewalls

While you can easily build an assembled desktop firewall for about the same price, here is why we recommend the NFW4125:

Consumes Less power – It only consumes 15W of power, which means it can be online on your UPS for a very long time as compares to a regular 500W desktop SMPS

Highly Reliable – Our firewall has no moving parts with passive cooling and so it is far more reliable than any assembled desktop that frequently fail due to SMPS, FAN and other failures.

Takes Less Space – Due to its compact size, It takes up the same space as your broadband modem or a wireless router. You can even mount it behind a monitor with the included VESA Mount Plate


Current use cases

Currently, this firewall is being used in a variety of industry verticals. 

Some use cases are:

– As a standard firewall to secure your network against hackers

– For website filtering at offices, schools, colleges, call centers, Industries etc.

– As a WAN load balancer to combine multiple internet connections for companies that need 100% uptime.
You can even use 3G / 4G routers for failover / loadbalancing

– At hotels / restaurants where you want to offer guest Wi-Fi with username / password or voucher based authentication.

– For connecting branch offices to the corporate office on standard broadband connections

Other use cases

This hardware can also be used as:

– Ubuntu Desktop / Server with GUI
– CentOS Desktop / server
– Windows Server (Supports windows 10)
– General Purpose Linux Server
– VoIP Server
– Virtualization (Proxmox / Vmware ESXi)
