Abstract: A system is provided for filtering packets. The system includes: a filter for determining, by applying a set of at least one filtering rule, whether a packet is permitted to be routed towards a receiving entity. The system includes a verification element for verifying validity of an authentication token included in a request received by the filtering system and adds, to the set, after receiving an initial request, a so-called top-level filtering rule, permitting the routing, towards the verification element, of at least one packet received via a predetermined communication port of the device, in which the source address is identical to the source address of the initial request, regardless of the source communication port of the subsequent request. A routing element routes a subsequent request including a valid authentication token towards a receiving entity of the subsequent request.

Abstract: The method of the invention comprises: a step of receiving a message (M1) sent by a user (T-B) of the first network, said message containing an access rule authorizing a user of a second network to access at least one multimedia content, said content being indexed with a content server (MS-B2) of the first network; a step of sending a first notification message (M2) to a trusted entity (PFS) managing the interface between the first network (NW-B) and the second network (NW-A), the first notification message (M2) containing a remote access rule (RAD) authorizing said user of the second network to access multimedia contents belonging to said user of the first network; and a step of commanding a gateway (HGW-B) of the first network (NW-B) by means of a local access rule configuring said gateway, such that said gateway transmits a catalog of contents to which said user of the second network is authorized to access on reception of an access request relating to said catalog coming from said user of the second ne
