Dashboard – OPNsense offers a dashboard feature to quickly check the status of your OPNsense Firewall.

Modern User Interface – OPNsense offers a dashboard feature to quickly check the status of your OPNsense

Stateful firewall – A stateful firewall is a firewall that keeps track of the state of network connections (such as TCP streams, UDP communication) traveling across it. OPNsense offers grouping of Firewall Rules by Category, a great feature for more demanding network setups.

Aliases & GeoLite Country Database – Managing firewall rules have never been this easy. By using Aliases you can group mulitple IP’s or Host into one list, to be used in firewall rules. Additionally IP or Hostnames can be fetched from external URLs, examples are DROP (Do Not Route Or Peer), Abuse.ch’s Ransomware tracker and the build-in Maxmind GeoLite2 Country database.

Traffic Shaper – Traffic shaping within OPNsense is very flexible and is organised around pipes, queues and corresponding rules. The pipes define the allowed bandwidth, the queues can be used to set a weight within the pipe and finally the rules are used to apply the shaping to a certain package flow. The shaping rules are handled independently from the firewall rules and other settings.

Two Factor Authentication – Two-factor authentication also known as 2FA or 2-Step Verification is an authentication method that requires two components, such as a pin/password + a token. OPNsense offers full support for Two-factor authentication ( 2FA ) throughout the entire system utilizing Google Authenticator.

Supported 2FA services include:

  • OPNsense Graphical User Interface
  • Captive Portal
  • Virtual Private Networking – OpenVPN & IPsec
  • Caching Proxy

Captive Portal – OPNsense offers a dashboard feature to quickly check the status of your OPNsense

VPN – OPNsense Comes with OpenVPN and IPsec

High Availability – OPNsense utilises the Common Address Redundancy Protocol or CARP for hardware failover. Two or more firewalls can be configured as a failover group. If one interface fails on the primary or the primary goes offline entirely, the secondary becomes active.

Caching Proxy – The caching proxy offered by OPNsense is fully featured and includes category based webfiltering, extensive Access Control Lists and can run in transparent mode. The proxy can be combined with the traffic shaper to enhance user experience. Integration with most professional Anti-Virus solutions is possble trough the ICAP interface.

IPS / IDS – The inline IPS system of OPNsense is based on Suricata and utilises Netmap to enhance performance and minimize cpu utilisation. This deep packet inspection system is very powerful and can be used to mitigate security threats at wire speed.

Reporting and monitoring – OPNsense offers many options for reporting and monitoring the system, these include:

System Health – A modern take on RRD graphs with the option to zoom in and export data.
Netflow Exporter – Use your favorite netflow analyser to see most active users, interfaces, ports & applications.
Intergrated Netflow Analyser –  OPNsense also offers an integrated Netflow analyser without the need for additional plugins or tools, similar to what you may find in high-end commercial products.

Firmware & Plugins – OPNsense offers a dashboard feature to quickly check the status of your OPNsense

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 OPNsense or want to switch to something else, you can easily install virtually ANY Linux / Unix based 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 4GB ram (that virtually support 4,000,000+ concurrent connections or more) start at Rs. 3 Lakhs !


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 NFW2C4:

Consumes Less power – It only consumes 6W to 10W 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!

POE Enabled – If you have a PoE switch, you don’t even need the power adapter. You can directly power the firewall with an ethernet cable from your PoE enabled switch


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
