I was checking Comcast website and I see they have blocked all those ports.

Shall, we simply add rule for each port and block them ?
And should it be done at the border or core or PPPoE router ?
add chain=forward protocol=tcp dst-port=0 action=drop
add chain=forward protocol=udpdst-port=68 action=drop
And so on...
But how to block? I mean, in microtik firewall it doesnt allow to enter range or tcp/udpboth at once.
