A gateway enables communications between a personal area network, such as a Zigbee network, and an Internet Protocol (IP) network. The gateway includes a first interface device for connecting to the personal area network, a second interface device for connecting to the IP network, and a gateway controller. In one embodiment, the gateway controller allocates ports on an IP interface to one or more clients in said personal area network, stores a routing table in memory for relating said clients in said personal area network with their corresponding ports, and transfers messages between said personal area network clients and said IP network based on entries in said routing table. In other embodiments, the gateway may function in conjunction with a gateway proxy.
