Hi,

I'm not entirely sure about your question.  The 'man iptables' shows for
'hashlimit' the following two tunable parameters which may address your
question(?):

       --hashlimit-htable-size num
              The number of buckets of the hash table

       --hashlimit-htable-max num
              Maximum entries in the hash

Cheers,
