Abstract: A method of providing secure access to a remote communication network via a local communication network for a terminal device. A gateway node located outside the local communication network allocates an IP address to the terminal device. The gateway node subsequently receives a request to establish a secure tunnel between the gateway node and the terminal device. It identifies the terminal device as the same terminal device to which an IP address is allocated, and allocates the same IP address for use by the terminal device as both an inner IP address and an outer IP address for packets sent via the secure tunnel. This ensures that there are no issues as described above in selecting the IP address for use in the secure tunnel, and reduces the risk of a successful man-in-the-middle attack.

Abstract: A method and apparatus for routing communications traffic in a Proxy Mobile IP communications network. A Mobile Node is attached to a first Proxy Mobile Agent, and an optimized route is established between the Mobile Node and a Corresponding Node via the first Proxy Mobile Agent. When the Mobile Node subsequently attaches to a second Proxy Mobile Agent, a determination is made that the Mobile Node is no longer attached to the first Proxy Mobile Agent.
