A technique for routing datagrams between customer equipments, CEs, (102) and a pool (110) of broadband network gateways, BNGs, (112) is provided. As to a device aspect (120) of the technique, a first establishing unit (122) is configured to establish a first connection (123) between the device (120) and each of the CEs (102). A second establishing unit (124) is configured to establish a second connection (125) between the device (120) and each BNG (112) in the pool (110) of BNGs (112). A mapping unit (126) is configured to map each of the first connections (123) to one of the second connections (125). The mapping specifies the routing of the datagrams.
