This is a modified instruction excerpt from the guide Beyond Cloudflare Tunnels: A High-Bandwidth Solution for Home Lab Remote Access seen on the StrangeMatter Blog.
This new instruction set specifies how to do a single application mapped to the gateway rather than a full through-traffic version. It focuses on vLLM as the expected usecase (but any application can be used).
On both the Gateway and the vLLM Server, I installed the latest headless Ubuntu. This is mostly because I am most familiar with the OS.
