That's why I was talking about filtering at a router just upstream from the dial-access box.
FWIW, even with a thousand very busy modems, I'm pretty sure that even a small cisco is up to the job. They just don't generate all that much traffic.
Could be, although I'd want to see this before I bet the farm on it. I'm not sure how efficient crisco's filtering algorithm is...
I would. As a point of reference, we have filters on two fairly busy T1s, which between them account for more then 500 modems worth of traffic and a *lot* more besides (all of VTW's traffic, for example). Putting filters on these, both an an AGS+/4, didn't make an enormous difference in CPU- it's still <30%. Surely a 2500 series box could handle that much. (It's 68030 vs. 68040, but we're at 30% utilization, and we're doing other things on that box.) /a --- Alexis Rosen Owner/Sysadmin, PANIX Public Access Unix & Internet, NYC. alexis@panix.com
