With DS-Lite you don't have a public IPv4. Not a static one but also not a dynamic one. The ISP just gives you a public IPv6. You share your IPv4 address with other users. This is done to use less IPv4s. But not having a dynamic IPv4 causes you to be unable to use DynDNS etc. It's simply not possible.
You could publish your stuff via IPv6 only but good luck accessing it from a network without IPv6.
You could also spin up tunnels with SSH actually between a public server and the private one (yes SSH can do stuff like that) but that's very hard to manage with many services so you're better of building a setup like mine.

Thanks for the great explanation!
