Overview

You can provide additional security to L2TP and IP tunnels by protecting them with an IPSec transport connection. Secure IP interfaces are virtual IP interfaces that are configured to provide confidentiality and authentication services for the traffic flowing through the interface; that traffic can be L2TP, GRE, and DVMRP tunnel traffic. See Configuring IPSec for detailed information about IPSec.

GRE, DVMRP, and L2TP over IPSec provide security only between tunnel endpoints; they do not provide end-to-end security. For end-to-end security, you need additional security for the connection beyond the router.
