The main goal of BSDRP is not firewalling but routing. If you are looking for a firewall, or for sharing your Internet access, don't use BSDRP but use m0n0wall or pfSense instead.
BSDRP doesn't have a Web GUI: It's to be configured from a CLI only (like Cisco/Juniper).
BSDRP is not intended for home use, but for company use (small ISP for example).
