Can nginx proxy manager reverse proxy non docker?

So i have a vm hosted on my proxmox server with docker and nginx proxy manager, it can reverse proxy any container on the same network “bridge” without any problems..

However, i have other vms on proxmox “non docker” that i eant to reverse proxy to it but I couldn’t do it… I tried using (network_mode: host) and (network: external) But it doesn’t seem to work, whenever i inspect docker network it always says that npm is running on bridge network..

Tldr I need containerized npm to reverse proxy other “non docker” proxmox vms
