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