I would like to configure an IDSM-2 in inline mode, I am having trouble about the deployment, I have a couple of questions;
1. If you configure 2 VLANs (existing) as VLAN pairs does this mean the exist connection between the 2 VLANs is broken?
ie they can only communicate to each other via IPS.
2. Where is the best place to deploy this type of IPS?
1. If configure properly, it will definitely not break any connectivity (its a bump in the wire). Of course if some traffic is denied by any IPS signature itself, that is a different matter. Please see this example for more help:
2. Inline mode is deployed where you want proactive protection and the the IPS box you have has sufficient throughput and other resources that will allow it to monitor that segment of your network (or multiple segments for that matter..)
