Abstract
A method of handling IP packets transmitted from a correspondent node to a mobile node via an intermediate node using the IPsec security protocol. The method comprises, at the correspondent node, identifying specified selector information within the part of the packet to be encrypted, and incorporating the identified information or a digest thereof into a header part of the packet which is to be sent unencrypted, transmitting the packet from the correspondent node to said intermediate node, and, at the intermediate node, receiving the transmitted packet and identifying a policy to be applied to the packet using said information or digest contained in the packet, and applying the policy to the packet.
