	Title		: Secure Remote Access with L2TP

L2TP protocol is a virtual extension of PPP across IP network
infrastructure. L2TP makes possible for an access concentrator(LAC)
to be near remote clients, while allowing PPP termination server
(LNS) to be located in enterprise premises. L2TP allows an
enterprise to retain control of RADIUS data base, which is used
to control Authentication, Authorization and Accountability (AAA)
of dial-in users. The objective of this document is to extend
security characteristics of IPsec to remote access users, as they
dial-in through the Internet. This is accomplished without creating 
new protocols and using the existing practices of Remote Access and
IPsec. Specifically, the LNS node, acting as Secure Remote Access
Server (SRAS), will mandate IPsec from remote clients, thereby
ensuring that all IP packets it receives across the Internet are
authenticated prior to injecting to enterprise network. The document
also discusses the configuration aspects of SRAS and its limitations.

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
