strongSwan

[[TOC(heading=Mobile IPv6)]]

= Mobile IPv6 =

Starting with version 4.2.9, strongSwan can be used to secure the Mobile IPv6 Binding Update messages and all payload traffic between a Mobile Node (MN) and its Home Agent (HA) using an IPsec transport and an IPsec tunnel Security Association (SA), respectively. For the installation and configuration of the IPsec-enabled Mobile IPv6 '''mip6d''' daemon consult Arnaud Ebalard's fine [http://www.natisbad.org/MIPv6/ MIPv6 site].
