In this paper, the authors address the security problems raised by the introduction of Mobile IP and Mobile IPv6 protocols into existing networks. First, a protocol-based analysis highlights several malicious attacks like masquerade, and denial of service. Then classical network architecture is studied for the best placements of mobility entities from the security point of view. Firewalls and, possibly NAT/NAPT devices should take into account the mobility dimension. Impact on the filtering rules enforced within a firewall is presented with inherent security risks.
