The present invention discloses a method and system for processing a first layer two packet converting a first layer two packet to a first unicast layer two packet at a wireless access point. The wireless access point receives first one or more layer three packets and extracts a first layer two packet from the first one or more layer three packets. If the first layer 2 packet is a multicast packet and it satisfies the predefined rule, the first layer two packet is converted to a layer two unicast packet with a first destination address and send to a Local Area Network (LAN) network interface. If the first layer two packet does not satisfy the predefined rule, it is broadcast to one or more LAN network interface. When the first layer two packet is not a multicast packet, it is sent to its corresponding destination address through one or more LAN network.
