Snort Blocking Kerio Webmail after log in
-
Having some issues with Snort blocking Kerio Webmail after a user has logged in. A user hits the External facing web page via SSL (Port 443) with no issues. Goes through login, gets a display of their email, but after clicking on 1 or 2, Snort will then flag the IP with the following information:
PROTO:255 (portscan) TCP Filtered Portscan 122:5:0
I turned off Port Scan Preprocessor completely and the alert stops showing up and the traffic is allowed. Is there a way I can fine tune the rules to allow this traffic and keep the Port Scan blocker on?
