Hi Timo/everyone,
Currently we are logging the remote IP, but is there a way to show the IP address that the NAT connection is coming from?
The reason I ask is, we are changing ISPs, and I would like to see in the logs when an external connection is coming from our OLD ISP connection, and when it is coming through our new one.
Traffic monitoring during a switchover of this nature is typically done at the edge router, not inside an individual server application. Is your router able to compile or export a daily traffic report per physical port, or raw data to your network monitoring software, showing packets/connections for TCP/UDP. Most can. This would give you the information you seek, including all traffic for both the new and old ISP, not just IMAP.
