Dropped as in dropped on the floor. I'm assuming you're using a Linux
based system from your use of iptables. If you are, be sure and have a
look at Phil Wood's libpcap magic . It's made quite a bit of
difference for some folks.

Depends on how much traffic is generated. Since you're looking at 'all'
traffic, you're using more CPU, RAM, I/O, etc... Try just looking at your
incoming stuff and see if you drop packets.
And please don't reply with the entire digest next time. :)
