strongswan-nm 4.3.2-1ubuntu2 (amd64 binary) in ubuntu karmic

 StrongSwan is an IPsec-based VPN solution for the Linux kernel. It uses the
 native IPsec stack and runs on any recent 2.6 kernel (no patching required).
 It supports both IKEv1 and the newer IKEv2 protocols.
 .
 This plugin provides an interface which allows NetworkManager to configure
 and control the IKEv2 daemon directly through D-Bus. It is designed to work
 in conjunction with the network-manager-strongswan package, providing
 a simple graphical frontend to configure IPsec based VPNs.
