Fedora supports IPsec
for connecting remote hosts and networks to each other using a secure tunnel on a common carrier network such as the Internet. IPsec
can be implemented using a host-to-host (one computer workstation to another) or network-to-network (one LAN
to another) configuration.
implementation in Fedora uses Internet Key Exchange
), a protocol implemented by the Internet Engineering Task Force (IETF
), used for mutual authentication and secure associations between connecting systems.
