The BACnet Firewall Router (BFR) is a BACnet router with security firewall functionality. As a firewall it allows network and address filtering plus network and application layer service filtering of BACnet communications according to a security policy. The BFR also has the ability to function as a BACnet Broadcast Management Device (BBMD) and provide Network Address Translation (NAT). The BFR is a piece of software that runs under Linux on a PC with two network cards (one facing the external network and one facing the internal protected network). The BFR is presently under development as a Sourceforge project (http://sourceforge.net/projects/bfr/); Sourceforge is a website that hosts many open-source software development efforts. Source code, user manual, and other details are available for free at Sourceforge.
