I have an ASA firewall with a built in IPS ASA-SSM-10.
When im running these in "inline" mode it appears sites we send outbound email using TLS will not work. I dont get any error messages in debug mode that the IDS's are blocking this traffic. If i change the IPS to "promiscous mode" the traffic passes. Has anyone else seen this problem and did you find a fix?
Thanks in advance
