Abstract
A method for pre-authentication in a wireless network is disclosed. The method begins by receiving, from a mobile client device, an Ethernet pre-authentication frame having an Ethernet address corresponding to a destination infrastructure device in the wireless network. Based upon a network mapping table, the method determines an internet protocol (IP) address that is mapped to the Ethernet address of the destination infrastructure device. The Ethernet pre-authentication frame is encapsulated inside an IP packet having the IP address. Then, the method routes the IP packet to the destination infrastructure device across WLANs with a different VLAN or subnetwork boundary in the wireless network.
