The problem with trying to throttle incoming bandwidth is that no matter what you do, you have already received the packets. As long as your internal network is faster than the external network feeding it, throttling incoming is useless: you've got the packets, putting them on your internal network won't slow things down, and dropping them will only cause them to get retransmitted. (And use up *more* of your already-scarce external connection.) Shaping outgoing traffic is useful because you can control which packets make it to the external chokepoint. Coming in, they've already made it through. Daniel T. Staal --------------------------------------------------------------- This email copyright the author.
