Is there a recommended design for PRTG to securely monitor systems in a less secure environment like a DMZ?
One of the practices we use is all communication from the less secure zone (DMZ) to the high secure zone (like an internal production network) can only be in response to requests from the high secure zone. Communication cannot be initiated from the DMZ to the internal network.
Can PRTG remote sensors be configured to only respond to requests from the master PRTG server?
Do you recommend a separate PRTG instance (master and remote sensors) to monitor resources in the DMZ?
