1. An apparatus comprising a processor, memory, and computer-executable instructions stored in the memory which, when executed by the processor, cause the apparatus to:
establish a first connection between the apparatus and a wireless transmit and receive unit (WTRU);
establish a second connection between the apparatus and a local gateway;
receive a message, wherein the message comprises an indication of a port number, an indication that a first traffic received by the apparatus is addressed to a first IP address corresponding to the WTRU, an indication that the first traffic is identified by the port number, an indication that the first traffic is to be addressed to a second IP address and routed to the second IP address via the local gateway, and an indication that traffic that is not identified by the port number is to be routed to the WTRU;
receive the first traffic, wherein the first traffic is identified by the port number, wherein the first traffic is addressed to the first IP address, the first IP address corresponding to the WTRU;
send the first traffic to the second IP address via the local gateway;
receive a second traffic, wherein the second traffic is not identified by the port number, wherein the second traffic is addressed to the first IP address, the first IP address corresponding to the WTRU; and
send the second traffic to the WTRU.
