Abstract
A network traffic hub is configured to receive a request for a port service (i.e., port forwarding or port triggering) from a smart appliance in a local network. The request may be a part of the UPnP protocol, which includes SSDP and IGDP. The request may be transmitted to the network traffic hub directly or the network traffic hub may intercept the request transmitted to a router of the local network. By receiving the request, the network traffic hub prevents automatic establishment of the port service between the smart appliance and the router until an approval or denial of the port service is received from a user. As such, the user is informed of the request and has the ability to approve or deny the port service. Furthermore, the network traffic hub can configure a network to perform a port service if the network does not allow for it natively.
