Abstract
A method and implementation are disclosed for binding a mobile node to a subnet. The invention comprises steps and implementations for intercepting messages sent by a mobile node to a server, associating a predetermined subnet with the intercepted messages and forwarding the intercepted messages to the server. The invention intercepts reply messages sent by at least one server, selects reply messages that are associated with the predetermined subnet. The selected reply messages are forwarded to the mobile node and reply messages that are not associated with the predetermined subnet are discarded.
