Bifrost is a lightweight distribution of Linux optimized for networking. It is named after Bifröst, the bridge which connects the world and the land of Gods in Nordic mythology. [1]

Primary Usage[edit]

Since the intended use is network infrastructure, reliability is the number one priority with performance a close second. It is trusted with mission critical deployments where uptime is measured in years.

The two most common uses are as Edge Router or NAC / Captive portal. Both of these uses often also perform at least basic firewall functions.


The first version of the Bifrost firewall was installed at The Department of Chemistry, Swedish University of Agricultural Sciences in the year 1997.


Currently the development, testing, and packaging is housed at Uppsala University with contributions from many other. The university also runs several installations where Bifrost is used. Bifrost is also used as a base for an authentication service, which make it possible to log in to the net.
