Abstract: In general, techniques are described for using virtual local area networks (VLANs) to facilitate packet forwarding between wireless endpoint devices attached to a wireless local area network (WLAN) access network and one or more mobile gateways providing access to packet data network services. For example, a wireless access gateway includes an upstream interface for a mobility tunnel to a mobile gateway of a mobile service provider network and a downstream interface for a WLAN access network. The wireless access gateway receives a packet from the mobile gateway by the upstream interface. The wireless access gateway determines, based at least on the mobility tunnel, a VLAN of the WLAN access network that is uniquely associated in the wireless access gateway with a combination of the APN associated with the mobility tunnel and the mobile gateway. The wireless access gateway then forwards, to a wireless endpoint device, the packet on the VLAN.
