IP Security (IPSec)
IP Security provides a mechanism for establishing secure tunnels from mobile subscribers to pre-defined endpoints (i.e.
enterprise or home networks) in accordance with the following standards:

RFC-3193, Securing L2TP using IPSEC, November 2001
IP Security (IPSec) is a suite of protocols that interact with one another to provide secure private communications across
IP networks. These protocols allow the system to establish and maintain secure tunnels with peer security gateways.
IPSec can be implemented on the system for the following applications:
IP networks. These protocols allow the system to establish and maintain secure tunnels with peer security gateways.
IPSec can be implemented on the system for the following applications:
PDN Access: Subscriber IP traffic is routed over an IPSec tunnel from the system to a secure gateway on the
packet data network (PDN) as determined by access control list (ACL) criteria.
Mobile IP: Mobile IP control signals and subscriber data is encapsulated in IPSec tunnels that are established
between foreign agents (FAs) and home agents (HAs) over the Pi interfaces.

:
Once an IPSec tunnel is established between an FA and HA for a particular
subscriber, all new Mobile IP sessions using the same FA and HA are passed over the tunnel
regardless of whether or not IPSec is supported for the new subscriber sessions. Data for existing
Mobile IP sessions is unaffected.

Mobile IP sessions is unaffected.
L2TP: L2TP-encapsulated packets are routed from the system to an LNS/secure gateway over an IPSec tunnel.
The following figure shows IPSec configurations.
