Windows Teredo says "secondary > server address unreachable". Because you are most likely still using the old servers which only support (afaik) the old 6bone prefix and not yet the 2001::/32 one. Also, did you reboot? :) > What is this configuration changed supposed to affect, exactly?

The v6 path is there, that is what GRH shows, though that still depends on the viewpoint and if the route is actually made visible globally or only for a limitted set of networks (eg using no-export or filters). The v4 path is the other question and you will have to configure it to use a server which supports the RIR prefix. That said, you will want to contact the operator of your Teredo server you are using, though you might some of them here, if you really want operational people and not standards folks, try: http://lists.cluenet.de/mailman/listinfo/ipv6-ops Though I have to note that that is not a help-me list either. > Is Teredo reliably and universally working with ANY configuration? According to the people who tested it it seems to work except for the cone-nat situation (or was it the other one, see wikipedia ;) > I have fond memories of those few times last year when a South Korean > public relay actually advertised the old prefix in global BGP, and > Teredo actually worked globally. Which was most likely quite useless latency wise when your packets had to travel twice around the world; it also makes debugging a lot of 'fun'. Greets, Jeroen
