I had a dual pentium 100 with 96 megs of RAM that did ipf/ipnat for a 10mbps connection with a couple dozen users. CPU usage was usually around 1% and load averages .03 or so. Latency and throughput were both acceptable. The only reason I replaced the box was it was a single point of failure and the hardware was old enough that I was afraid there would be some sort of show stopper breakdown. -- Thanks, Josh Paetzel _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
