I've just confirmed that doing that, on RELENG_5_1 and RELENG_4, does result in ping 255.255.255.255 sending ICMP packets out with that dest addr. I have not personally tested UDP on FreeBSD, but this hack used to work on Irix, which at least back then had a bsd-derived network stack, to enable bootp to work with no kernel mods. -- Barney Wolff http://www.databus.com/bwresume.pdf I'm available by contract or FT, in the NYC metro area or via the 'Net.
