Hi All, Question being asked about Microsoft Exchange here due to the packets you may have noted being blocked by the firewall, so anybody who has experienced the same traffic pattern, please let me know.
Note in the firewall log, burst of traffic from our Exchange servers being sent to/from arbitrary ports to external IP addresses. Packets dropped/rejected, as they should be as it is denied unknown/denied protocols. The scenario is that we run WebOutlook services, and I suspect that the Exchange servers are trying to communicate directly with the system with the client running the WebOutlook URL loaded in their browser. This rejected traffic does not impact any functionality. Client on Internet communicates with HTTP front-end on DMZ, which in-turn communicate with Exchange server on secure internal network. However I want to how to terminate this arbitrary traffic, so it doesn't show up repeatedly in the logs....but without using any masking rules which don't block. ( I haven't been able to find a thing ay Microsoft which points to any issues) So upshot, anybody experienced this behavior with WebOutlook and traffic attempting to traverse security points? Thank you for your time.
