A method in a network node for handling a traffic flow of a User Equipment, UE is provided. The network node is related to a first local service cloud, and the traffic flow is related to an application session served by the first local service cloud. The network node creates (202) a unique Network Address Translated, NAT:ed, Internet Protocol, IP, address mapping to an UE IPaddress of the UE. The unique NAT:ed IP address comprises a local IP address prefix assigned to the first local service cloud. The unique NAT:ed IP address is enabled to be used for the traffic flow both before and after a handover of the UE from the first local service cloud 111 to a neighbouring second local service cloud. The unique NAT:ed IP address is unique at least in all local service clouds neighbouring to the first local service cloud 111, including the second local service cloud. The network node assigns (203) the unique NAT:ed IP address to the UE for local break out of the traffic flow of the application session to the first local service cloud. |
