Method and apparatus for indicating that connection enables routing of data between pdn gateway and local gateway

A method performed by an apparatus, comprising:

• establishing a connection between the apparatus and a gateway;
• receiving 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 a wireless transmit and receive unit (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 gateway, and an indication that traffic that is not identified by the port number is to be routed to the WTRU;
• receiving the first traffic, wherein the first traffic is identified by the port number and addressed to the first IP address, the first IP address corresponding to the WTRU;
• sending the first traffic to the second IP address via the gateway;
• receiving the 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
• sending the second traffic to the WTRU via the gateway.

A non-transitory, computer-readable medium comprising computer-executable instructions which, when executed by a processor, cause the processor to:

• establish a connection between an apparatus and a gateway;
• receive a message, wherein the message comprises an indication of a port number, and an indication that a first traffic received by the apparatus is addressed to a first IP address corresponding to a wireless transmit and receive unit (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 a second IP address via the gateway.
