Technical Details

what runs on :36411

WLCP is the Wireless LAN Control Plane Protocol specified by 3GPP for WLAN access to 5GC. It uses UDP port 36411; UDP has no connection handshake, and WLCP messages support the protocol's WLAN control procedures. This is not a general-purpose Wi-Fi management service, and a listener is expected only in compatible 3GPP access implementations. The port assignment alone does not establish particular message framing or protection details for an implementation.

security overview

This is control-plane signaling intended for a specific operator-access context, not a service that should be exposed to the public internet. UDP itself provides no encryption or peer authentication; restrict access to the relevant trusted network and rely on the deployment's applicable access and security protections. Public scan data does not show this port as commonly open.
