1) When snort reports that packets are dropped, should I take that to mean that they are dropped on the floor or just that Snort couldt look at them fast enough so it skipped them? I want to montior traffic, but not at the expense of packet loss.
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 [0]. It's made quite a bit of difference for some folks.
2)I have a LAN on one side of this box with about 100 clients and a connection to a gig E backbone on the other side. Is my snort box configuration reasonable? Should I be droppping packets consistently?
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. :) Cheers! ----- Erek Adams "When things get weird, the weird turn pro." H.S.
