NAT traversal....???? http://www.spectrum.ieee.org/select/1098/int.html NATs are a no-no HEATH: I was going to say that IEEE Spectrum should make it very clear that this group's consensus would appear to be: let's discourage NATs--I mean the manufacture of them at all--because there is a real need for IPv6. HUITEMA: It's more than that. There is a real need for security and you can't have security with NATs. CERF: NAT is a guaranteed spoofing box in effect. ============================================================ ----- Original Message ----- From: "Dan Freedman" <dan@fsa.ca> To: <ietf@ietf.org> Cc: <sip@ietf.org> Sent: Tuesday, March 25, 2003 9:43 AM Subject: RE: [Sip] Eating our own Dog Food...could the IAB and IESG use SIP for conference calls Agreed. To enable access from behind firewalls (ie: homes, hotels, conferences, airports, Asia, ...), we can donate a B2BUA-based NAT traversal solution for SIP (same one that Pulver's Free World Dialup uses). It sits near the proxy, with nothing needed on the client end. Bottom line: In addition to helping the IESG and IAB, it will help SIP to have more IETF participants gaining experience with it. -Dan Dan Freedman, CEO, Jasomi Networks, Inc. 2033 Gateway Place, Suite 500, San Jose, CA, 95110 Phone +1.403.680.2351 Fax +1.403.269.2993 Email dan@jasomi.com SIP dan@jasomi.com Web www.jasomi.com -----Original Message----- From: sip-admin@ietf.org [mailto:sip-admin@ietf.org] On Behalf Of Jiri Kuthan Sent: Tuesday, March 25, 2003 8:01 AM To: Henry Sinnreich; 'Richard Shockey'; ietf@ietf.org Cc: sip@ietf.org; Scott Petrack; Christian Stredicke That's great idea.
