Document: draft-ietf-v6ops-tunnel-security-concerns-04.txt Reviewer: Brian Carpenter Review Date: 2011-01-05 IETF LC End Date: 2010-12-29 IESG Telechat date: 2011-01-06 Summary: Almost ready -------- Technically this document is fine. I have a concern that the document may be read entirely negatively as advice to block all tunnels, whereas in fact Section 7 (briefly) describes precautions that would make the use of tunnels relatively safe as part of v4/v6 coexistence. After a short dialogue with one of the authors (Suresh), I would like to see the reader's attention drawn to this early in the document.
