L2TP over IPSec
L2TP over IPSec VPNs enable a business to transport data over the Internet,
while still maintaining a high level of security to protect data.
You can use this type of secure connection for small or remote office clients that
need access to the corporate network. You can also use L2TP over IPSec VPNs for
routers at remote sites by using the local ISP and creating a demand-dial
connection into corporate headquarters.
