Hi everybody,

A couple weeks ago I promised people I'd write a patch that integrates
ipf into FreeBSD's startup scripts.  Here's what it does:

Rearranges some things in rc.conf (relative to freebsd-current from a
couple days ago, cvs tag in the diff), adding a number of features.

Rewrites rc.firewall to:

  1) Use either ipf, ipfw, some third party program, or nothing at all

  2) Auto generate a sensible rule list, if configured to do so in rc.conf

Creates rc.nat, the nat equivalent of rc.firewall

rc.nat also generates a sensible rule list, if configured to do so.

Updates rc.network to work with the new system

Two additional files are introduced, /etc/nat.conf and /etc/firewall.conf.
This is where the associated rules are stored.  This is a change from the
ipfw configuration being stored in the middle of rc.firewall.

In order to not bog down the list, you can download the patch at:

All feedback would be much appreciated.  I'd really like this to go into
freebsd 4.0, or have something resembling this to go in.
