I am in the process of installing a 4215 using 2 different inline pairs.
I have a reverse-proxy server on one tier of a firewall protected by 1 inline pair which then redirects traffic back through the IPS and the firewall to the web servers on a web tier (seperate interface on the firewall) and through the IPS again on a different inline interface pair.
For some reason, when I set the IPS to inspect (on or auto) the setup doesn't work. The IPS isn't reporting any blocked traffic or denies or events. I can go directly to the web servers and that works. As soon as I set the IPS to BYPASS all traffic the setup works.
I havent' installed a license on the IPS because I am still waiting for it from Cisco but I believe that the setup should work without it, unless I am mistaken???
Does anyone know what the problem could be? Could it be related to the reverse-rpoxy receiving traffic and the forwarding the traffic back through the IPS?
Any assistance would be greatly appreciated!
