IPF: The IP Filter
This introduction discusses
IPfilter. Setup is described for FreeBSD, but that shouldn't be much
of a difference on NetBSD (see... um, where's our generic firewalling
documentation?). The text discusses what a firewall is, basic and more
advanced filtering like on interface or on IPs and advanced topics
like defaulting to deny (beware to not lock traffic to lo0 :), keeping
state and IPv6.
