Lock Down Management Access

Anyone on the office network can currently try to log into the core router — fix that

场景

A routine security assessment found that the core router's remote management interface (used for administrative configuration access) is reachable from every subnet in the building, including regular employee workstations and guest Wi-Fi — anyone on the network can attempt to connect to it, not just the small IT team who should be the only ones able to. You've been asked to restrict management access to the dedicated IT administrative subnet only, without affecting the router's normal job of routing traffic for everyone else.
