Technical Summary

  This document outlines a solution for the Mobile IPv4 and IPsec
  coexistence problem for enterprise users.  The solution consists of
  an applicability statement for using Mobile IPv4 and IPsec for
  session mobility in corporate remote access scenarios, and a required
  mechanism for detecting the trusted internal network securely. The
  solution requires only changes to the mobile node; changes to Mobile
  IPv4 or IPsec protocols, the VPN gateway, or the home agent are not
  required.

Working Group Summary

  This is a product of the MIP4 WG, and has the backing of the
  WG. It has emerged from the work done by the VPN traversal
  design team.

Protocol Quality

  This specification has been reviewed by Henrik Levkowetz, Vijay
  Deverapalli, Jari Arkko, and members of the MIP4 WG.

Note to RFC Editor

  In Section 5.2, change:

  OLD:
   The overhead consists of the following:
  NEW:
   The maximum overhead of 97 octets in the 'cvc' access mode
   consists of the following: 

  Also, please change s/abovementioned/above mentioned and
  s/untypical/atypical throughout the document.

  Add to the end of the IANA Considerations section:

    Allocation of new Sub-Type values can be made via
    Expert Review and Specification Required [I-D.narten-iana-
    considerations-rfc2434bis].

  And add draft-narten as a new normative reference.
