The present invention aims at making it possible for a data packet originating from a mobile network node (102, 103) in a moving network (101) to be routed over any of a number of external accesses (111, 112) accessible from different mobile routers (104, 105) in the moving network to home networks (115, 117) related to the moving network, for the case where the mobile routers advertise different address prefixes to the mobile network nodes. When a mobile router (104) advertising a first address prefix receives a data packet associated with a source address with the first address prefix, and the mobile router selects, for routing to a home network, an external access (112) accessible from another mobile router (105) advertising a second access prefix, the mobile router will: detect that the source address of the data packet has an address prefix different to the second address prefix, provide the data packet with a different source address having the second address prefix, and transmit the data packet to the other mobile router for subsequent transmission via the selected external access (112) to a home network (117) of the moving network.
