Acknowledgments

  The bridge was originally developed as an undergraduate independent study at the University of North Carolina at Greensboro by Jason L. Wright with Dr. Suzanne Lea as an advisor. The code was contributed to the OpenBSD project and integrated into the source tree prior to the 2.5 release (May 1999).

The authors would also like to thank Theo de Raadt and Jonathan Smith for their suggestions and support during the course of this work. Theo de Raadt suggested many of the original concepts behind the filtering bridge and the virtual LAN. This work was partly sponsored by DARPA under grant F39502-99-1-0512-MOD P0001.
