I used to get scanned by my ISP alot when I was in TX... so I figured out the IPs they scanned me from, banned them on my firewalls.... and called and complained to them that I knew what they were doing and felt that they were disturbing my privacy and ruining my service at the same time because it would almost allways kill my connection when they did it. I was VERY vocal when I spoke with them and threatend to drop my service if this didn't stop.... so guess what.... it stopped

It should at least give you some ideas as to which ports you can use if you don't know.
