Serviio

Hi,

my new provider (Unitymedia Cable) has only IPv6 Addresses. No possibility to get an IPv4-Address (using DS-Lite-Tunnel , IPv4 over DS-Lite). No dual stack possible.
Now I have a fixed IP-adress (IPv6) but no chance to get contact with serviio from outside. ServiiGo does´t work. Also my dyndns accout (selfhost.me) only accept IPv4-addresses.
Great, I have no access but with 100Mbit.

I'm not an expert, but wouldn't that be the job of the router? Ie your external IP is v6 and router forwards the port to yout v4 local serviio address.

I'm not an expert either, but I belive it's not quite that simple, they aren't just different address schemes, they are completely different (and incompatiable) protocals. So you need an end-to-end IPv6 or IPv4 link, or otherwise you need to create a tunnel to bypass the section of the network that only supports one of them.

Is this a residential line or some form of hosted solution? It seems very odd to me that an ISP would provide absolutely no means for IPv4 access even for a dedicated server, as although IPv6 uptake is increasing, the majority of services are IPv4 only. Also, unless you get IPv6 via you phone provider as well, the only thing I can think of is to setup your own tunnel to a dedicated server which has support for both. I've setup a IPv6 over IPv4 tunnel via HE before, but not the other way around, I guess there must be providers out there that will be your endpoint.
