Yes, but not necessarily?
I guess a NAT66 device is quite happy with processing the first 40 bytes
only. Not clear what's the exact purpose of these sentences
(definition of what a middlebox is or the fact that other parts
are also of interest for middleboxes),
but probably it's better to insert a "may also" before "inspect other".

 Roland
