This violates RFC1812 <ftp://ftp.rfc-editor.org/in-notes/rfc1812.txt>, which mandates that subnet broadcast packets must be passed on as specified in STD3 <ftp://ftp.rfc-editor.org/in-notes/std/std3.txt>. This actually is no longer good practice, so I'd say it's more prudence than an outright design flaw that FreeBSD doesn't comply with this. -- -- Skylar Thompson (skylar_at_cs.earlham.edu) -- http://www.cs.earlham.edu/~skylar/
