Some embodiments of the present application relate to the field of gateways for internet access, associated video service decoders and the methods for broadcasting video content by an operator through such a gateway intended for such a decoder. A virtual MAC address is dedicated to VOD on the decoder. This address is then recognized by the gateway. The gateway implements a direct circuit directly directing the traffic related to this virtual address between the interface for accessing the communications network and the gateway physical port to which the decoder is connected. Advantageously, the circuit is dynamically configured by intercepting the DHCP request used to configure this virtual address.
