racoon2 is a system to exchange and install security parameters for IPsec. It consists of an IKEv1/IKEv2 key exchange daemon, a security policy management daemon, and a Kerberos-based key exchange daemon. The project lives at zoulasc/racoon2 and is being modernized so that it can serve as a reliable L2TP/IPsec or IKEv2 VPN server on NetBSD and Linux for built-in Windows, iOS and Android VPN clients.
