how do you want to 'block' them? you want it to stop alerting? or you
want to block them via 'dropping' packets?

check out portscan2-ignorehosts, its the same function that preprocessor
portscan had.
That seems like what your attempting todo.

Hope it helps... Just my 8cents, the other 2 are free! :-)
