The answer to the upcoming question must be obvious to many people here, but anyway not to me: Does blocking RH2 breaks Mobile Nodes in your network, or does it break both Mobile Nodes *AND* Correspondant Nodes? In the later case, it might be worth mentioning that "blocking RH breaks connectivity toward external peers completely (or almost)". This looks more terrifying to me that "blocking RH prevents deployment of future technology". In fact, whether you and I like it or not (I hate it), firewalls are quite often blocking "future technology" on purpose. In the poor real world of IT, there are some network administrator that are responsible for the security of their perimeter. There are seldom responsible for new technology not working out of the box. It's a truth, we'd rather adapt to, if we can.
