A multi-domain network comprises a first network domain, e.g., a fixed access domain, and a second network domain, e.g., a cellular network domain. The first network domain includes a gateway (24) providing a first access to a packet network. The second network domain includes a further gateway (14) providing a second access to the packet network. A policy controller determines an anchoring rule for controlling whether the gateway (24) selects a first route (25) or a second route (15) for data traffic of a user equipment. The first route extends between the gateway (24) and the first access, and the second route extends, via the further gateway (14), between the gateway (24) and the second access. Further, the policy controller sends control data to control application of the anchoring rule by the gateway (24).
