The invention relates to a system (GW2) for filtering packets, including: a filtering means (MF) for determining, by applying a set of at least one filtering rule, whether a packet is permitted to be routed towards a receiving entity; a means (RP) for verifying the validity of an authentication token included in a request received by said filtering system; a means (RP) for adding, to said set, after receiving an initial request, a so-called top-level filtering rule, permitting the routing, towards said verification means (RP), of at least one packet received via a predetermined communication port of said 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; and a means (RP) for routing a subsequent request including a valid authentication token towards a receiving entity of said subsequent request. |
