Please send substantive comments to the ietf@ietf.org mailing lists by 2012-02-20. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract Due to specific problems, NAT-PT was deprecated by the IETF as a mechanism to perform IPv6-IPv4 translation. Since then, new efforts have been undertaken within IETF to standardize alternative mechanisms to perform IPv6-IPv4 translation. This document evaluates how the new stateful translation mechanisms avoid the problems that caused the IETF to deprecate NAT-PT. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-behave-64-analysis/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-behave-64-analysis/ No IPR declarations have been submitted directly on this I-D.

Document: draft-ietf-behave-64-analysis-05 Title: Analysis of Stateful 64 Translation Reviewer: S. Moonesamy Review Date: February 16, 2012 Summary: This draft is almost ready for publication as an Informational RFC. This draft evaluates how the new stateful translation mechanisms avoid the problems that caused the IETF to deprecate NAT-PT. It discusses about problems identified in RFC 4966. There is an analysis about an application protocol (FTP) in Section 2.2. Applications are mention in several places. I did not find any application issues. Major issues: None. Minor issues: In Section 2.2: "Analysis: This is not specific to NAT64 but to all stateful NAT flavors. The presence of single point of failures is deployment-specific." Wouldn't the anchoring of flows create a single point of failure? "Actually, this is not a limitation of 64 (or even NAT-PT) but a deployment context where shared IPv4 addresses managed by the NAT64 are not globally reachable." What is meant by "shared IPv4 addresses" in this context? In Section 2.3: "Application clients (e.g., VPN clients) are not aware of the timer configured in the NAT device. For unmanaged services, a conservative approach would be adopted by applications which issue frequent keepalive messages to be sure that an active mapping is still be maintained by any involved NAT64 device even if the NAT64 complies with TCP/UDP/ICMP BEHAVE WG specifications." I suggest point to the relevant IETF specifications. For what it's worth, this draft becomes an IETF specification instead of a WG specification once it is published as a RFC. "Address persistence can be therefore easily ensured by the NAT64 function (which complies with BEHAVE NAT recommendations [RFC4787][RFC5382])." I recommend against writing a draft from a working group perspective unless it is meant for IETF consumption only. In Section 5: "This document does not specify any new protocol or architecture. It only analyzes how BEHAVE WG 64 documents mitigate concerns raised in [RFC4966] and which ones are still unaddressed." From Section 1.1, I am given to understand that there are references to mechanisms defined in the RFCs mentioned in that section. There isn't any mention of BEHAVE WG 64 documents. I suggest referencing the documents. There is a normative reference to RFC 2766, which is Historic. Nits: The Requirements language section is oddly placed. In Section 2.3: "Creation of a DoS (Denial of Service)" That could be "Creation of a Denial of Service (DoS)". Some of the informative references are out of date. Regards, S.

Can you please clarify? Thanks. If we are talking about the BEHAVE WG, IETF participants either know about it or can look it up. If you say "which complies with BEHAVE NAT", a wider audience would not know what BEHAVE is. It's easier to say "complies with NAT recommendations in [RFC4787][RFC5382]". >I can do but IMHO the document does not introduce new security concerns, no?

We'll post = the minutes to the list shortly. The same day, our AD informed all TSV WG chairs that Paris has an extremely= tight schedule and was looking for groups willing to give up a slot. We discussed the results of our in= terim in that context and have decided to schedule probably 2 WebEx interims, one shortly before Paris and one sho= rtly after Paris in lieu of taking up a scarce meeting slot. This means there will be no Behave session in P= aris. We hope that work will continue and that people will actively participate in the WebEx interim(s).

Title : Analysis of Stateful 64 Translation Author(s) : Reinaldo Penno Tarun Saxena Mohamed Boucadair Senthil Sivakumar Filename : draft-ietf-behave-64-analysis-06.txt Pages : 15 Date : 2012-02-21 Due to specific problems, NAT-PT was deprecated by the IETF as a mechanism to perform IPv6-IPv4 translation. Since then, new efforts have been undertaken within IETF to standardize alternative mechanisms to perform IPv6-IPv4 translation. This document evaluates how the new stateful translation mechanisms avoid the problems that caused the IETF to deprecate NAT-PT.

Hello,

 

RFC 6146, section 3.5.2.2, says that in V6 FIN RCV s= tate *any* packet other than V4 FIN must set the session lifetime to= no less than TCP_EST=3D2hours.

 

If the V4 target sent RST in response to the transla= ted V6 FIN, what is the reason to keep the NAT mapping alive for TCP_EST in= stead of TCP_TRANS?

 

Should the language “if a V4 FIN packet is rec= eived,… lifetime is set to TCP_TRANS” be changed to “if a= V4 FIN or V4 RST packet is received,… lifetime is set to TCP_TRANS&#= 8221;?

Supports ne= w MIB for CGN/NAT realities Should 4008bis obsolete or update RFC 4008 PROPOSED CONSENSUS: 4008bis obsoletes not updates RFC 4008 (2 people for, none against) only 1 person spoke up (Reinaldo) as representing an implementation or= =20 possibility Should NAT64 additions be in separate doc or same doc PROPOSED CONSENSUS: No preference, up to authors as to whether NAT64 object= s are in same doc Simon: Should 4008bis include CGN features or be in a separate draft? Reinaldo: CGN in same draft as NAT64 might not work? Thaler: separate CGN from 4008bis Marc Blanchet: keep drafts separate and combine at last minute as needed =3D=3D=3D Reinaldo - 4787/5382/5508bis (TCP/UDP/ICMP) --- requirement for endpoint-independent filtering (EIF) generates derived=20 requirements some are updates to values or clarifications some are brand new example: creating TCP state for track sequence numbers have per-TCP session= =20 state even when mapping is static, if implementation does that then=20 need to mitigate security state attack If endpoint-independent mapping (EIM) exists for TCP, can a UDP packet use= =20 the mapping? Senthil: TCP reset handling is ambiguous Address Pooling Paired - can you use ports from another IP when you're out= =20 of ports? transitory (half open/closed) idle-timeout: RFC requires 4 minute min. Reinaldo proposed allowing it to be set lower because some implementations= =20 provide such a knob. Dan: which of these issues cause interop problems if we don't clarify them? or are these just quality of implementation issues? Dave: sounds like quality of implementation Reinaldo: document the security issues Dave: For example, bar for changing the MUST NOT (4 minutes) is higher=20 because it was a consensus document Simon: many items came from list discussion on CGN requirements to not forg= et=20 about them Arifumi: transitory idle timeout related to time-wait state ACTION: chairs to review document and send questions for the WG to discuss= =20 to the list =3D=3D=3D Senthil - CGN logging Main feedback was to define a transport protocol to carry the info no answer from the list on preference on which protocol so planning to use IPFIX (one person in meeting last IETF suggested syslog= =20 though) IEs are not well defined, so making clarifications barring any feedback, will use binary Simon: can you estimate log size? Senthil: about 30 bytes per mapping in a normal case Dan: how compressable is it? Senthil: don't know Dave: this is about on-the-wire not a log-on-disk Dan: there's been complaints about lots of data storage per subscriber but= =20 haven't seen anyone talking about compression Dan: how many NAT records can fit in the same message on the wire? ACTION: Senthil to add to doc how many NAT records can fit in the same=20 message on the wire Suhas: a lot of duplicated information? =3D=3D=3D Suhas - TURN URI Context is RTCWeb TURN server may be hard-coded in every RTCWeb client (browser) OR provision= ed in javascript to the client Dave: we got pushback against URI before. So why URI and not something els= e=20 like a JSON structure? Marc: URI wasn't standardized before because there was no use case where UR= I was needed at the time ACTION: authors to get rtcweb chairs to comment on URI vs. JSON object vs. whatever Dan: haven't seen discussion on the Behave WG list, and if past experience is an indicator, there probably won't be =3D=3D=3D Chairs planning for another interim in 2 weeks or so (sometime around March= 2) From wwwrun@rfc-editor.org Wed Feb 29 11:04:28 2012 Return-Path: X-Original-To: behave@ietfa.amsl.com Delivered-To: behave@ietfa.amsl.com Received: from localhost (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id E915C21F858F; Wed, 29 Feb 2012 11:04:28 -0800 (PST) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -102.13 X-Spam-Level: X-Spam-Status: No, score=-102.13 tagged_above=-999 required=5 tests=[AWL=-0.130, BAYES_00=-2.599, J_CHICKENPOX_93=0.6, NO_RELAYS=-0.001, USER_IN_WHITELIST=-100] Received: from mail.ietf.org ([12.22.58.30]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id QoQz-wzsNMVV; Wed, 29 Feb 2012 11:04:28 -0800 (PST) Received: from rfc-editor.org (rfc-editor.org [IPv6:2001:1890:123a::1:2f]) by ietfa.amsl.com (Postfix) with ESMTP id 33D4821F8554; Wed, 29 Feb 2012 11:04:24 -0800 (PST) Received: by rfc-editor.org (Postfix, from userid 30) id 1558D72E08A; Wed, 29 Feb 2012 10:58:46 -0800 (PST) To: ietf-announce@ietf.org, rfc-dist@rfc-editor.org From: rfc-editor@rfc-editor.org Message-Id: <20120229185846.1558D72E08A@rfc-editor.org> Date: Wed, 29 Feb 2012 10:58:46 -0800 (PST) Cc: behave@ietf.org, rfc-editor@rfc-editor.org Subject: [BEHAVE] RFC 6535 on Dual-Stack Hosts Using "Bump-in-the-Host" (BIH) X-BeenThere: behave@ietf.org X-Mailman-Version: 2.1.12 Precedence: list List-Id: mailing list of BEHAVE IETF WG List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 29 Feb 2012 19:04:29 -0000 A new Request for Comments is now available in online RFC libraries. RFC 6535 Title: Dual-Stack Hosts Using "Bump-in-the-Host" (BIH) Author: B. Huang, H. Deng, T. Savolainen Status: Standards Track Stream: IETF Date: February 2012 Mailbox: bill.huang@chinamobile.com, denghui@chinamobile.com, teemu.savolainen@nokia.com Pages: 25 Characters: 54452 Obsoletes: RFC2767, RFC3338 I-D Tag: draft-ietf-behave-v4v6-bih-09.txt URL: http://www.rfc-editor.org/rfc/rfc6535.txt Bump-in-the-Host (BIH) is a host-based IPv4 to IPv6 protocol translation mechanism that allows a class of IPv4-only applications that work through NATs to communicate with IPv6-only peers. The host on which applications are running may be connected to IPv6-only or dual-stack access networks. BIH hides IPv6 and makes the IPv4-only applications think they are talking with IPv4 peers by local synthesis of IPv4 addresses. This document obsoletes RFC 2767 and RFC 3338.
