Hi Dennis, I am guessing that your "32Mbs" would be a 16Mbps frac T3 line, bidirectional? I was reliably routing 5000pps the other day on a Pentium 100... and it did not seem particularly stressed out. Has anybody set up the equipment to actually _try_ this? It would be interesting, no doubt :-) ... JG
