I need some help regarding a deployment of a IPS module on a ASA. I configured it in transparent mode, with the intention to only monitor the traffic going through the module. Otherwise after aplying the policy and put it in operation, it started blocking SMTP and ICMP traffic. Here follows the configuration applied to it:
ips promiscuous fail-open
service-policy outside-policy interface outside
Is there anything else I should consider to put this module just monitoring the traffic instead of having it denying any traffic?
Thanks in Advance
