>Description:
Channelling for Paul Hoffman:

ipnat needs ip forwarding turned on in order to be anything more than
a waste of kvm.

There should be an rc.conf setting for IPv4 ip forwarding allowing you
to tweak this one way or the other.

/etc/rc.d/ipnat should notice if/when sysctl net.inet.ip.forwarding is
turned off and either whine, or fix it itself (exactly which doesn't
really matter to me).

>How-To-Repeat:
	turn on ipnat, don't turn on IP forwarding, be confused for a bit.

>Fix:
	probably small.
