How to route IPv6-only client through IPv4 host?

[rcd]

So I have a host with both IPv4 and IPv6 connectivity - that works.

How can I route traffic from a IPv6 client through the hosts IPv4 interface?

I've spent hours googling, and it seems this should be possible, for example by tunnelling the traffic through one of several protocols like 6to4, Teredo, ISATAP, or GRE - but I can't find any examples of how to do it. Essentially my objective is just to avoid having to add an IPv4 interface to the clients just to download the odd package only available on IPv4.

You want to make IPv4 destinations available to your IPv6 host?
Then you need a proxy/gateway that translates between IPv6 and IPv4.
If it's only for downloading packages squid may work for you.

Thanks, yes that would of course solve the problem but I wasn't actually precise. My objective is also to learn and understand how IPv6 works.

Is there no way to do this through the proxmox bridge?

A bridge is on layer 2. You want to translate beween IPv6 and IPv4, that's layer 3 and above.
