from the 4.9 relnotes:

ipfw(8) can now modify ipfw(4) rules in set 31, which was read-only and
used for the default rules. They can be deleted by ipfw delete set 31
command but are not deleted by the ipfw flush command. This implements a
flexible form of ``persistent rules''. More details can be found in
ipfw(8).


I haven't actually done it yet for myself, but it would seem that 65535
can be changed now. (?)
