If one wanted to go this way, one could easily use an unsigned char or

With unsigned char one can address that 256 table what is too too 
with shorts int, one can address 65535 table it is more acceptable but 
too is can for the large ones numbers rules. That becomes correct 
from 3 bytes, which gives 16 million table, but 3 bytes it is 
dealigned in
the memory, therefore the best choice remains 4 bytes, and which more 
that is the fastest solution on the most current architecture.
For me 4 octets it"s the big value for lot of rules and the less value 
small memory use.
I thought 256 would be enough as the firewall has a binary tree with 
256 nodes each level.
