I would love to read further details on netmap filtering on real NICs, because the default info is about vale: ports and not netmap: ports and yes, for vale ports it works very nice > > > On Thu, Nov 6, 2014 at 2:27 PM, Evandro Nunes <evandronune...@gmail.com> > wrote: > >> On Wed, Nov 5, 2014 at 10:40 PM, Evandro Nunes <evandronune...@gmail.com> >> wrote: >> >>> On Wed, Nov 5, 2014 at 8:44 PM, Patrick Tracanelli < >>> eks...@freebsdbrasil.com.br> wrote: >>> >>>> Hey, what you are doing wrong is much more simple than you expect. >>>> >>>> > # ./kipfw em1 em2 > & /tmp/kipfw.log & >>>> > [1] 66583 >>>> >>>> Just run ./kipfw netmap:em1 netmap:em2 and this will probably work. >>>> >>>> Please remember to redirect kipfw output to somewhere you are not >>>> reading only *after* you are sure the output is showing errors.
