Features of this implementation

1 Due to the implementation is working at user space, one of the constrains we have found is the impossibility of answering to the foreign agent's ARP request. ARP answers have been disable. In order to avoid the problem of answering FA's ARP requests, the Mobile Node issues periodically and ARP reply addressed to the FA. With this, the FA updates its ARP entry (associated with the MN) and it does not issue any ARP request.
