6.3. IPsec Installation

Implementing IPsec requires that the ipsec-tools RPM package be installed on all IPsec hosts (if using a host-to-host configuration) or routers (if using a network-to-network configuration). The RPM package contains essential libraries, daemons, and configuration files to aid in setup of the IPsec connection, including:

Configuring IPsec on Red Hat Enterprise Linux can be done via the Network Administration Tool or by manually editing networking and IPsec configuration files. For more information about using the Network Administration Tool, refer to the Red Hat Enterprise Linux System Administration Guide.

To connect two network-connected hosts via IPsec, refer to Section 6.4 IPsec Host-to-Host Configuration. To connect one LAN/WAN to another via IPsec, refer to Section 6.5 IPsec Network-to-Network configuration.
