Remote access even with DS-lite

[LinkDarkshire 0]

So I don't know if this is the right place to ask this but I hope someone can help me.
So here's the situation: I changed my ISP a few days ago. My previous one offered DualStack but I didn't pay attention if my new one does. And unfortunately he doesn't, which means I only have DS-Lite. This ensures that I can not access the server outside my home network. Now the question is: Does anyone know how I can implement remote access despite this obstacle ? On the internet some said it could be done with portmapping but unfortunately I only found tutorials that cover a small part. If someone has a good tutorial on how to do this with an Nvidia Shild Pro I would be very grateful.
