David, What volume of traffic do you have to manage everyday and how much time do you actually spend managing that traffic. Im assuming that you do have the IDS on the outside of the firewall? This was the crux of Richs question. If your IDS is on the outside of your firewall can you tell me what the reason is?

We are thinking of putting a Snort-based sensor outside our firewall in the Untrusted zone. (This is after the border/edge/gateway router which is controlled by our hosting facility and not us.) I was wondering if any of you had any advice about: 1. OS: Linux? Hardened how? What system capacity (RAM, hard drive) might be required? 2. Cabling setup: Internet Cat 5 cable to hub and cable from hub to sensor and cable from hub to Untrusted port of firewall? (I've tried this in the past and had problems with traffic even getting to the firewall. Maybe a crossover cable is needed?) Many thanks in advance for any advice/experience you would offer.
