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/
WAN to another) configuration.
The
IPsec implementation in Fedora uses
Internet Key Exchange (
IKE), a protocol implemented by the Internet Engineering Task Force (
IETF), used for mutual authentication and secure associations between connecting systems.
