Alex,

No. Depends on how you tie the Mobile IP and IKE session. Sure, if you use
CoA for IKE/IPsec, your IPsec session is dead after each Mobile IP handoff.

Instead, use the HoA for IKE transaction; Mobile IP offers mobility to
HoA. IKE/IPsec session is an application using that HoA :)

The result is Mobile VPN :) It works, we had a product on Windows many
years back.
