    AFAIK it doesn't support symmetric NAT.

    Indeed, it does not.

    So double NAT might work based on the NAT methods used by the firewalls/routers.

    I just did a few tests with my laptop that has a 3G broadband interface. The connection is IPv4 only. When I make a connection I get an address in the 100.64.0.0/10 range. So I am behind a CGNAT.

    I also get an IPv6 address in the Teredo range. But it does not work. The IPv6 test say I have no IPv6. I can not ping test6.vlist.eu or wrt6.vlist.eu. The Teredo address is not pingable from my fixed broadband connection.

    Forget about Teredeo. It is not reliable.


    Cheers, Michiel

    Didn't MS announce that they will shut down their Teredo service?
    [..]

    was it not just work aslong as xp is supported ?, eg is windows 7 supporting there fails ?

    I was not aware that it was linked to XP's sunset. Anyway, Teredo had better be disabled. It causes more problems than it solves.

    yes only duggi have no ipv6 yet here to save me memory in dual
    stacking, its my plan to move to oswald its native ipv4 and ipv6

    I don't understand why in this day and age you make an issue of saving a few kb of memory. "640K ought to be enough for anyone" has been history for decades...

    ----- miredo.ebuild begins -----
    * net-misc/miredo
    Available versions: 1.2.5-r2^t 1.2.6^t {+caps}

    Description: Miredo is an open-source Teredo IPv6
    tunneling software

    ----- miredo.ebuild ends -----

    protocol is opensource and still supported in gentoo

    Forget about Teredo or Miredo. Get a real tunnel, works much better and safer.
