Adding an external Security Onion sensor node to an internal manager node through NAT ???

[ducanh31195]

Is there a guide for adding an external Security Onion sensor node to an internal manager node through NAT?

I am deploying a Security Onion Distributed architecture within an internal network environment with no Internet access.

I'm trying to add a sensor node located on an external network to a manager node behind NAT (internal network). However, when I attempt to download the repository or connect to the manager via its NAT IP, the connection gets redirected to the manager's internal IP, which is not accessible from the external sensor.

Is there any documentation or recommended approach to handle this NAT scenario properly?
