strongswan-libfast 5.1.2~dr2-0ubuntu1 (amd64 binary) in ubuntu trusty

 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.
 .
 libfast is a small library built around libfcgi and ClearSilver. It wraps these
 libraries properly and integrates session management and a MVC-like
 architecture. It targets embedded systems or servers where processing power and
 footprint is limited and should work with any FastCGI capable webserver.
