AFAICT, the translators themselves are just rewriting addresses and not paying attention to 'connections', which is all to the good. But then we get to this: ----- 5.2. Recommendations for Application Writers Several mechanisms (e.g., STUN [RFC5389], Traversal Using Relays around NAT (TURN) [RFC5766], and Interactive Connectivity Establishment (ICE) [RFC5245]) have been used with traditional IPv4 NAT to circumvent some of the limitations of such devices. Similar mechanisms could also be applied to circumvent some of the issues with an NPTv6 Translator. However, all of these require the assistance of an external server or a function co-located with the translator that can tell an "internal" host what its "external" addresses are. ----- ----------------------------------------------------------------------- Roland Dobbins <rdobb...@arbor.net> // <http://www.arbornetworks.com> The basis of optimism is sheer terror. -- Oscar Wilde
