A method and arrangement for enabling access to a home device in a private network from a remote device located outside the private network. The private network includes a multimedia gateway connected to a multimedia service network. A session invite message is sent from the remote device to the multimedia gateway. In response, connection parameters of a residential gateway in the private network are sent to the remote device, which are associated with the selected home device if a home device identification was included in the received message, or with a proxy function in the multimedia gateway capable of providing home device information, if no such identification was included in the received message. In this way, home devices in the private network can be easily and safely accessed remotely.
