IMO, Commercial ISPs should never filter customer packets unless specifically requested to do so by the customer, or in response to a security/abuse incident.
Let's say the customer operates some big enterprise network, runs their infrastructure in RFC1918 space ("for security," hah), and spews a couple kilobits of DNS query from that RFC1918 space toward the root nameservers. Assume that either pride or ignorance will prevent the customer from ever asking you to filter what you know to be garbage traffic. Does your rule to "never filter customer packets" mean you're going to sit and watch those packets go by? If yes, why? Stephen
