Yes !

I couldn't use FreeBSD without it .. no .. maybe that's a bit strong .. I'd
just have to learn a bit more about Cisco's access-lists :-) 

However, the order rearrangement forces a particular strategy when building
ipfw scripts that requires considerable patience by virtue of not always
producing the expected (and desired) results. 

On the other side, I understand that searching a rule tree similar to that
found in the routing tables is of considerable performance advantage as
compared to the traversal a (possibly lengthy) singly linked list ..

It's swings and roundabouts,
