Normally whatever you are comfortable with. Just monitor it for a few weeks and modify to your preference. Remember also your ISP may be scanning for server services on your network if it's not a business internet account.

Does anyone else use this and what are the settings you use. I believe I set it to 10 ports before classifying it as an "attack". Is this too low?
