Hello, i'm playing around with IPv6 for university matters (and myself) and ran into some problems with my configuration. Situation: 1. My 6in4 Tunnel with my /48 subnet runs on a dedicated server (Linux) with a public IPv4 Address and a small IPv4 subnet. 2. My home network ist connected via NAT to an upstream provider (dynamic ip) with a linux router within this private ipv4 network. Goal: Assign and tunnel a /64 subnet to the network behind that NAT'ed router. Could it be possible to connect the NATed router from (2) via teredo/miredo and build up some kind of a "tunnel" to my server (1) to get a /64 subnet routed into my home-network? I know, OpenVPN might be a better solution. But what is with something like "6in6" (which might be nearly like "not implemented" in Linux at the moment)?? Or, are there any other "easy" solutions without OpenVPN, to tunnel and route ipv6 traffic between a Sixxs'ed Server and several "co-locations" behind NAT-gateways?? Thanks for help!
