Abstract
A method of managing switching of a virtual private network (VPN) tunnel termination point from a first address to a second address. The VPN operates between a fixed network node and a mobile node which defines the termination point. The address of the mobile mode is switched from the first address to the second address and a notification from the mobile node to the fixed node is sent to indicate that the address of the mobile has changed from the first address to the second address. Verification of the trustworthiness of the second address is also then made. A searching manager for performing the method is also disclosed.
