The OPNsense software is based on FreeBSD(R) and is customised for use as a firewall and router. It contains almost all the functions of expensive commercial firewalls, in many cases even more. Here are some of the supported features:

– Firewall
– State table
– NAT
– Redundancy
– Load balancing for outgoing and incoming connections
– VPN – IPsec, OpenVPN, PPTP
– PPPoE server
– RRD graphic reporting
– Real-time information – with AJAX
– Dynamic DNS
– Unprotected portal
– DHCP server and relay
– Live CD version available

The OPNsense software runs on an energy-saving APU4D4 system, so that the average power consumption is a maximum of 10 watts. The system is fanless, passively cooled and extremely small.
