portsentry alternative

I installed portsentry on a server, and I have been reading about how people can take advantage of it. Well i think i experienced that when it added some 30000 ip addresses to be blocked within a few minutes.

So does anyone know of any good alternatives, i am considering bastille, but i am going to test that out before i put it on a server to be sure i dont lock myself out.
