I know that, and I try to explain it to my customers... but it doesn't answer the first part of the question - what will throttling ICMP do to ping and traceroute times? My gut reaction is that it will a. slow them down and/or b. discard a lot of them making the circuit look unreliable to ping. But I don't know enough about the underlying technology to be sure of that. -- Jeff Shultz Network Support Technician Willamette Valley Internet Not speaking for anyone but myself here.
