strongSwan

<abbr title="heading=Mobile IPv6">TOC</abbr> = 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.
