Quote from=20 http://lists.freebsd.org/pipermail/freebsd-net/2014-November/040380.html = = WITHOUT kipfw you will be OUT of communication. If you want to have communication without kipfw please configure if_bridge(4) properly. My testing boxes , I could communicate with bridge + kipfw ,=20 but not without bridge , is that normal ? ( I have tested , after kipfw = with bridge , filtering rules still could be applied ) And do kipfw could be enable as multithread for a single bridge to = provide better performance ? Thank you so much .
