You have deployed a new media application that remains unreachable from external networks. It is located behind a device that modifies IP addresses for connectivity. Logs show inbound requests do not reach the internal resource. Which action helps fix the issue?
Create a port mapping rule for inbound traffic to reach the internal host
Change the server to another subnet and refresh the interface addresses
Include more encryption protocols on the external interface
Modify the public domain records for the media application
Forwarding from the device’s external interface to the internal service is necessary. A mapping entry directs traffic to the correct IP and port. Adjusting domain records or installing encryption protocols does not fix the missing forwarding rule. Reassigning subnets does not configure external traffic flow through the device.
