About Libreswan
Libreswan is an open-source implementation of IPsec and Internet Key Exchange (IKE) for building and managing encrypted virtual private network connections. It supports IKEv1 and IKEv2 and negotiates security associations between systems using IPsec, with capabilities including certificate-based authentication and NAT traversal. The software runs as an installed network service on Linux and several BSD systems, using the host operating system's IPsec stack. Administrators configure connections and credentials through configuration files and command-line tools, and can review tunnel status with the included ipsec utilities. Libreswan can be used to connect compatible IPsec peers for site-to-site or remote-access VPN deployments. It is intended for network administrators and security professionals who need to configure and operate IPsec VPN gateways or endpoints.
