UPNP device.


UPNP device. See UPNP for UPNP discovery and utility functions. Provides low-level access to UPNP control commands. Allows to manage port mappings (port forwarding) and to query network information of the device (like local and external IP address and status). Note that methods on this class are synchronous and block the calling thread.

  • IGD_STATUS_HTTP_EMPTY = 2 --- Empty HTTP response.
  • IGD_STATUS_NO_URLS = 3 --- Returned response contained no URLs.

Method Descriptions

Adds a port mapping to forward the given external port on this UPNPDevice for the given protocol to the local machine. See UPNP.add_port_mapping.

  • int delete_port_mapping ( int port, String proto="UDP" ) const

Deletes the port mapping identified by the given port and protocol combination on this device. See UPNP.delete_port_mapping.

  • bool is_valid_gateway ( ) const

Returns true if this is a valid IGD (InternetGatewayDevice) which potentially supports port forwarding.

  • String query_external_address ( ) const

Returns the external IP address of this UPNPDevice or an empty string.
