I wanna to use a Captive Portal to do user a= uthentication and use ip6fw and dummynet to do bandwith control.

As per the 7.0 Release notes found here: http://www.freebsd.org/releases/7.0R/relnotes.html >>>The ip6fw(8) packet filter has been removed.

Take a look at the FreeBSD handbook for a start on how to use ipfw: http://www.freebsd.org/doc/en/books/handbook/firewalls-ipfw.html and IPv6 = here: http://www.freebsd.org/doc/en/books/handbook/network-ipv6.html And of course, make sure to: 'man 8 ipfw' for all of the details, or peruse online here: http://www.freebsd.org/cgi/man.cgi?query=3Dipfw Make certain to read the section labeled "TRAFFIC SHAPER (DUMMYNET) CONFIGURATION" Good Luck. -_Dave > > So I wanna know is the ip6fw has been compiled into the GENERIC kernel? I= f not, how can I compile it into kernel or as a loadable kernel module? And= what about the dummynet? If dummynet unavailable, can you give me some adv= ises to limit bandwith?
