Talk:Protecting your customers
Over All I think it is a good first step to protect your networks but noticed in your suggested ports to block you are blocking VOIP ports. Beaware 5060-5061, 10000, and 16384 are voip ports.
basically it is good to block everything except the ports that you use. so first you have to individually find out what ports should be left open, then block everything else.
