The OPNsense software is based on FreeBSD(R) and was designed for use as a firewall and router. It includes almost all the functions of expensive commercial firewalls, and in most cases even more. For example, the following functions are provided (excerpt):

Firewall
Status table
NAT
Redundancy
Outgoing and incoming load balancing
VPN - IPsec, OpenVPN, PPTP
PPPoE server
RRD Graphs Reporting
Real-time information - with AJAX
Dynamic DNS
Captive portal
DHCP Server and Relay
Live CD version available

The OPNsense software runs on a power-saving APU2E4 system and has a maximum power consumption of 10 watts, which has a minimal impact on the environment. The system is fanless, passively cooled and extremely small (6 x 6").

APU2E update: The size of the battery socket has been changed to avoid contact problems. Added signal integrity resistor for core voltage control signal
