RE: Multiple network segment monitor with Snort

Try using the Top Layer IDS Balancer. The ROI is immediate!.

The IDS Balancer allows you to:
a) Aggregate traffic from various network segments into the input ports
(from taps or SPAN/Mirror ports)
b) Filter traffic in way you like
C) Create multiple copies of the same traffic (if you like)
d) Distribute the traffic in a very flexible way to the IDS sensors (load
balancing, n+1 redundancy, mix and match IDS sensors from different
vendors).

Our customers use the IDS Balancer as an Intelligent Layer 7 Patch Panel to
help them build a centralized intelligent monitoring layer, to attach your
monitoring devices (IDS sensors, sniffers, traffic analyzers, content
inspection and in general any monitoring device that works in promiscuous
mode).

I know that. But Cisco routers are very expensive. I was looking for 
cheaper solutions. My first desing used a Layer3 switch, but then I 
changed my mind (because of an impossibility for my netscreen border 
router to define more than two zones), and used a cheaper design (but I 
think that also less secure and manageable) with no Layer3 switch, but 
two Layer2 ones. Do you know any cheap Layer2 or Layer3 switch with 
mirror ports?

Thank you.
