RE: [Nolug] Cox Problem?

Hi Ray.

You are correct, however I've never heard of anyone setting ping limits in the
1 packet per second range. Perhaps 1000 packets per second, yes.

PingPlotter also supports ICMP, TCP and UDP packets. It's really a neat
utility! I use it and MultiPing constantly. http://www.pingplotter.com Only
bad thing is that they are Windows only.

It is possible they are rate-limiting ICMP for both forwarded and local
packets. Unfortunately ICMP has become less useful than it once was for
network troubleshooting... we have Windows worms to thank for this.

There is an app out there called "tcpping" that will "ping" an IP using
tcp SYN packets on any open port to measure latency. You might give that
a shot also.
