Reverse-proxying from a docker network (lemmy.dbzer0.com)

Hello, I have a question regarding the usage of a reverse-proxy which is part of a docker network.

I currently use Nginx Proxy Manager as a reverse-proxy for all my services hosted in docker. This works great since I can simply forward using each containers name. I have some services however (e.g. homeassistant) which are hosted separately in a VM or using docker on another device.

Is it possible to use the same reverse-proxy for those services as well? I haven't found a way to forward to hosts outside of the proxies docker network (except for using the host network setting which I would like to avoid)

This. Also, make sure the proxy is proxying websocket traffic as well. I do it with pure nginx like this:

server {
    listen 80;
    server_name example.com;

    location / {
        proxy_pass http://192.168.1.100:8123/;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;

        # WebSocket support
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}
