I'm a little concerned that this overrides the meaning of the rule
numbers.  Now they will define what order rules are processed and
whether they can be flushed.  Wouldn't it be more orthogonal to add a
flag to each rule (like the log keyword) to mark permanent rules?  I
don't know anything about the ipfw code, so maybe this is impractical
(and I'm sure it would require more work), but it sounds worth it to me.

I'd certainly love to have this feature, but I think it would be more
intuitive & useful as a per rule flag.  If this matter is going to be
discussed at length, it should probably move to -security and/or -ipfw.
