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@cs.earlham.edu) -- http://www.cs.earlham.edu/~skylar/ [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (Cygwin) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFB0ePhsc4yyULgN4YRAnffAJ9rNtScAYToVLf5tyKT41tQMNo0yACfc6Vj 37CQErxjwJs/ihZvHD1MJSE= =fM7i -----END PGP SIGNATURE-----help
