Enabling remote management is not a feature of a firewall. Firewalls are primarily responsible for closing network ports, filtering incoming packets of data, and blocking spam emails to protect the network against unauthorized access and potential threats. Enabling remote management, on the other hand, typically refers to the ability to remotely administer or control network devices, such as routers or switches, and is not directly related to the core functionality of a firewall.
