The local IP address for a specific TCP connection row in the connection table, noting a listening socket willing to accept on any interface reports 0.0.0.0. This lets an admin see, per active connection, exactly which of the gateway's own IPs a session is bound to, useful on a multi-homed appliance to confirm the management API is only being reached via the intended management IP and not accidentally exposed on a customer-facing address. Example: finding a tcpConnLocalAddress entry showing the external interface's IP for a connection to the management port would reveal the service is unexpectedly reachable from outside, not just internally as intended.
