  1. Recommendations for filtering ICMP messages(draft-ietf-opsec-icmp-filtering) Fernando Gont UTN/FRH 76th IETF meeting, November 8-13, 2009 Hiroshima, Japan

  2. Changes from the last rev • Populated a few sections • Updated outdated references • Miscellaneous edits • Progress was slow… but now commiting more cycles to it

  3. Open Issues • The document is currently heading for Informational. • Some suggested BCP • BCP might be a better target (personally, I’m happy either way) • Got some positive comments for aiming at BCP • Current advice assumes what to do with ICMP messages that go “through” the device • Should advice also address filtering messages from/to the device? • Got some positive comments about this idea

  4. Moving forward • Currently working working on the ICMPv6 sections • Rest of the document still needs work/review • If you have feedback, post it on opsec@ietf.org, or send it to fernando@gont.com.ar
