+    StrongSwan is direct descendant of the discontinued FreeS/WAN project.
+    As an IPsec based VPN solution which is focused on security and ease of
+    use, it fully implements the IKEv1/IKEv2 protocols, MOBIKE, NAT-Traversal
+    via UDP encapsulation (incl. port floating) and Dead Peer Detection. It
+    also fully supports the Linux 2.6 IPsec stack, IPv6, certificates/keys on
+    Smartcards and virtual IP address pools.
