Isn't it advisable for every tcp port you want to block?
I have some documentation that says that doing otherwise
it's even bad for your network communications.

The only people for me are the mad ones -- the ones who are mad to live,
mad to talk, mad to be saved, desirous of everything at the same time,
the ones who never yawn or say a commonplace thing, but burn, burn, burn
like fabulous yellow Roman candles.
