> Dear All,
> I would like to have a meeting at the IETF (informal BOF?) discussing
> methods for VoIP and Multimedia over IP traversing non-upgraded firewalls
> and NATs.  These methods are intended to supplement the firewall
> architecture, and not require upgrade to existing firewall/NAT components,
> or clients (and other infrastructure such as proxies).
> There is a draft discussing one proposal at:
> http://www.ietf.org/internet-drafts/draft-davies-fw-nat-traversal-00.txt
> If others have ideas in this area, then please contact me and we can
> some sort of agenda.  (Although note that I will be out of contact until
> Sunday before the IETF - i.e. this Sunday! - so we might have to organise
> this at the IETF.)
> I hope the format will be something like:
> - Overview presentation of method
> - How this is secure and maintains administrator control
> - (Repeat for each proposal)
> - Collect issues that need to be addressed before going to a formal BOF.
> (The modified agenda involves the final item being changed to 'chaos'!)
> At this stage I would like to avoid discussion about how this compares to
> MidCom and other approaches - such as Rosenberg's - as I think it will
> quickly turn into a blood bath.  - We should save that for the formal BOF!
> I'm hoping to hold the meeting in:
>     The King's Suite/Sandringham 1 on
>     Thursday 17:45 -> 18:45,
> but I obviously haven't had a chance to check this with the organisers.
> Therefore, please look out for final details on the noticeboard, and
> probably the door of the King's Suite.
> I look forward to seeing you all,
> Pete.
> (P.S.  Sorry for putting this on the SG16 and TIPHON lists, but I'm well
> aware that many of you attend the IETF and I wanted to make sure you had
> opportunity to come along.)
