Justin, I understand and share your concern. Unfortunately I cannot tell you since I have no idea what you use. In our case, we test them with unrealistic loads (all ports running ttcp) which is much more than a typical user will ever do. Adding such a filter is quite minimal in our case since our algorithms are pretty tight. Pat R.

How much spare processor do a lot of the dial access servers have left on them? I am somewhat concerned about the amount of processor left on my dial access servers.
