A method in a home base station for forwarding of data packets, wherein said home base station has a connection to at least one mobile terminal over a radio interface, a connection (5, 8) to a number of local nodes of a local network, and a connection to a core network of a mobile telecommunications system via an access network, said method comprising: receiving a number of uplink data packets from the mobile terminal over a number of bearers; characterized by further comprising: examining an address field of an uplink data packet received from the mobile terminal to identify a destination address associated with the uplink data packet; choosing if the packet is to be subject to local transportation and/or core transportation based on the identified destination address, wherein local transportation implies forwarding the uplink data packet to a local node over the local network without passing the core network, and core transportation implies forwarding the uplink data packet to the core network; replacing a source address of the uplink data packet with an address of the home base station, and creating a network address translation state in the home base station if the uplink data packet is chosen for local transportation, and replacing a destination address of a downlink data packet with an address of the mobile terminal using the network address translation state if the downlink data packet is destined for the mobile terminal and is received over the connection (5,8) to the local network, and forwarding the uplink data packet in accordance with the chosen type of transportation; wherein the home base station checks if the uplink data packet is excluded from local transportation, wherein the uplink data packet is excluded from local transportation if the bearer over which the uplink data packet was received from the mobile terminal is not a best effort bearer; and the home base station forwards the uplink data packet in accordance with the chosen type of transportation comprises forwarding the uplink data packet by means of core transportation if the uplink data packet is excluded from local transportation. receiving a number of uplink data packets from the mobile terminal over a number of bearers; examining an address field of an uplink data packet received from the mobile terminal to identify a destination address associated with the uplink data packet; choosing if the packet is to be subject to local transportation and/or core transportation based on the identified destination address, wherein local transportation implies forwarding the uplink data packet to a local node over the local network without passing the core network, and core transportation implies forwarding the uplink data packet to the core network; replacing a source address of the uplink data packet with an address of the home base station, and creating a network address translation state in the home base station if the uplink data packet is chosen for local transportation, and replacing a destination address of a downlink data packet with an address of the mobile terminal using the network address translation state if the downlink data packet is destined for the mobile terminal and is received over the connection (5,8) to the local network, and forwarding the uplink data packet in accordance with the chosen type of transportation;
