I think using Dmitry's idea of rejecting the first 2 connections, but then allowing it as normal on the third attempt would satisfy your requirements for being on the normal port, allowing all IPs and requiring no special setup on the client end (other than knowing they have to to retry twice). Of course, this is assuming the botnet stops after rejected connections...
