A new Request for Comments is now available in online RFC libraries. RFC 3024 Title: Reverse Tunneling for Mobile IP, revised Author(s): G. Montenegro, Editor Status: Standards Track y Date: January 2001 Mailbox: gab@sun.com Pages: 30 Characters: 63929 Obsoletes: 2344 I-D Tag: draft-ietf-mobileip-rfc2344-bis-03.txt URL: ftp://ftp.isi.edu/in-notes/rfc3024.txt Mobile Internet Protocol (IP) uses tunneling from the home agent to the mobile node's care-of address, but rarely in the reverse direction. Usually, a mobile node sends its packets through a router on the foreign network, and assumes that routing is independent of source address. When this assumption is not true, it is convenient to establish a topologically correct reverse tunnel from the care-of address to the home agent. This document proposes backwards-compatible extensions to Mobile IP to support topologically correct reverse tunnels. This document does not attempt to solve the problems posed by firewalls located between the home agent and the mobile node's care-of address. This document obsoletes RFC 2344. This document is a product of the IP Routing for Wireless/Mobile Hosts Working Group of the IETF. This is now a Proposed Standard Protocol. This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited.
