Routing a network to an host

    Hi all!

    Since a couple of year I used an IPv6-Tunnel over a vServer of mine (connected with native IPv6 from the Provider).
    Since last friday, Deutsche Telekom give me native IPv6-Subnet, but dynamic(!!), so that I get a new /64 network every time I restart my DSL...

    Well, I'd like to use my /64-Network I have on my vServer, so that I can have a static IPv6 (why the evil Telekom assign DYNAMIC IPv6-Network?!?) but routing it over the dynamic IPv6.
    Unfortunately, I can't get it working... :(

    I thought I can just change the end-point, but it does not work...

    Current situation (with IPv6-Tunnel):
    - transition network aaaa:bbbb:cccc:1000::/64 on my vServer and my PC at home
    - aaaa:bbbb:cccc:2000::/64 on my vServer an my PC at home. The vServer routes to network over aaaa:bbbb:cccc:1000::2, which is the IPv6 of my tunnel at home
    - xxxx:yy:zzz:kkkk:4d7a:1ed0:2105:1bc0 on my ppp0-interface at home

    I tried to change the route for aaaa:bbbb:cccc:2000::/64 using the new IPv6, but I get "RTNETLINK answers: No route to host".
    The command is: "ip -6 route add aaaa:bbbb:cccc:2000::/64 via xxxx:yy:zzz:kkkk:4d7a:1ed0:2105:1bc0 dev eth0 metric 1", which is almost the same of theone I use for my tunnel (ip -6 route add aaaa:bbbb:cccc:2000::/64 via aaaa:bbbb:cccc:1000::2 dev ipv6tun-1 metric 1).

    I think, I can't use the interface ipv6tun-1 with the new IPv6, so I can't understand how I can route my network over the "dynamic IPv6" of Deutsche Telekom...

    Any help is appreciated!

    Do they give any reason why? I have, sadly, no experience with ISPs
    offering IPv6, but it seems to me making it dynamic removes most of
    the benefits of IPv6 ...

    (No opinion on your actual question; sorry.)

    Of course, the "reason" is not meaningful...
    I know! But, since they have no idea what IPv6 really is (and many other things, too...), I can just decide to use it or not...
    And now is "not"... :)

    Grrr ...
    Well, someone /must/ have set it up at the ISP side, so /someone/
    there knows ... but that someone has obviously not been involved in
    designing the business case. Such a waste.
