Is there a way to control the amount of UDP traffic flowing through a router ? I am seeing excessive amounts of UDP traffic going through out internet router , specifically the NAT tables. I suspect some or other P2P app. but these things use dynamic port numbers which make it very dificult to control via ACL.
I am thinking you could use an extended access list and specifically allow one UDP port (e.g. NTP), all others would be denied automatically by the implicit deny. Not sure if this works, but maybe worth trying.
