I don't believe this will do what's wanted - the packets will not actually go thru the NICs, as the OS is smart enough to realize that the dest is internal. With a crossover cable (not required with gigabit nics) you can't tell, so if you try it use a switch and look at the lights. -- Barney Wolff http://www.databus.com/bwresume.pdf I never met a computer I didn't like. _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[EMAIL PROTECTED]"
