Sorry about the delay. It never notified me I had a response, and that project was temporarily suspended in lieu of another project.
To get back into the discussion as time is coming up, you are correct that the communication goes both ways:
A ↔ B ↔ C
I appreciate your solution and it is a good thought. The downside (that I neglected to mention) is that there is also a DMZ Z that is only able to communicate (both ways) with A. So moving the LEM into the newer B Network (essentially another DMZ) is not as feasible. That's why I was hoping for a log-forwarder option. Something that could collect and forward the logs to the LEM without actually having to build another, separate, LEM instance.
Thank you for your input and reply.
