Publish Server Port Forwarding
An internal service works locally but is not reachable through its approved public port.
Cenário
Dovetail Research is exposing a small internal service to an approved external client. The server works from inside the network, but the public-facing address does not currently deliver the requested service. Publish only the required port to the intended server and keep unrelated internal services unreachable from outside.
