Dear RRG Fellows - During the design of Six/One Router, I spent much of my energy on finding a translation-based solution that, even when deployed unilaterally and thus not transparent to applications, would avoid as much as possible of the problems of IPv4 NAPT.
More recently, many of the issues that motivated this earlier work have again come up in the discussion around IPv6 NAT (aka "NAT66"). I hence decided to document my earlier analysis as input to this discussion: http://users.piuha.net/chvogt/pub/2009/draft-vogt-address-translation-harmfulness-02.txt The analysis looks at potential problems of different address translator designs, and evaluates the cost and completeness of solutions to those problems. Although the analysis is written for the IPv6 NAT community, I believe it has value also here within RRG. Comments appreciated. - Christian PS: On terminology: The "one-to-one address translator" evaluated in the analysis is what Six/One Router uses in Unilateral mode. _______________________________________________ rrg mailing list [email protected] http://www.irtf.org/mailman/listinfo/rrg
