Dedicated Server (Virtualizor IP Pool) + GRE IPs?

I have a dedicated server with Virtualizor installed, I want to be able to create an IP pool and assign IPs to the vps (IPs from Noez.de). I am running into issues and im unsure of what to do. I create a ticket and they said to look around community, and virtualizor support agent told me to come here. Does anyone know how to get it working?
