/lib/ndb/fw names it, fw(8) uses it in two examples, and the service
file passes it as the rule file.  Nothing provided it, so following any
of them got you a firewall that would not start.

Written for the qemu NAT segment this is developed on: the local /24
first, since the gateway and the resolver both live there, then name
resolution and the web, icmp so there is something to test with that
does not need a name resolved first, and one port answered on.

Calvin's; committed so the tree stops referring to a file that is not
in it.
