Well, this is a question of the userland interface of any particular firewall set, be it ipfw, pf or ipf. The kernel and pfil API is not in the way of doing it. > Note that the ability to use a global filter is also still perfectly > appropriate for a host vs a router.

I'm a fan of KISS. Sure we can do and become everything for everyone with two gazillion sysctls and one-thousand compile time options but it's not going to scale and only a minority will use it at any given time. -- Andre _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[EMAIL PROTECTED]"
