We open only a few ports. Such as 80. Almost nothing else is open. The email is from our exchange server so it has rights to the ports it needs. This wiped out P2P and online gaming at the office and our internet speeds returned.
Hope this helps.

Is there a way to restrict the use of P2P? I know that shaping would place some restrictions on this. However programs such as Bitcomet and Limwire do they uses a specific port or protocol that could be shutdown or restricted by bandwidth? I have noticed that my ADSL 512 connection changed overnight going from 52Kbs to 2Kbs?
