Technical Summary
   Deploying Mobile-IP v4 in networks which are connected to the
   Internet through a VPN (Virtual Private Network) gateway presents
   some problems which do not currently have well-described solutions.
   This document aims to describe and illustrate these problems, and
   propose some guidelines for possible solutions.
Working Group Summary
The document was produced by a design team under the mobile-ip WG,
and also received input from non-wg members.  A security review was
done by Radia Perlman, and suggestions from that review incorporated
in the draft.  I believe the draft has been sufficiently reviewed.

Protocol Quality
This document has been reviewed for the IESG by Thomas Narten.
