How to set up HTTP forwarding from droplet to rPi?

I have the following setup:

  1. DO Droplet running Ubuntu 18 with Tinc VPN (server)
  2. rPi in remote location also running Tinc connected to server

The rPi is behind a router/firewall that I have no control over, so I can’t port forward there.

When I ssh to the DO droplet, I can then ssh to the rPi using the VPN address. So the VPN is working.

I need to be able to open a browser window on a random client machine and connect to a port on the DO server which will connect me to the rPi. Specifically, the rPi is running node-red, so it’s port 1880.

I tried setting up a proxy using NGINX to do it, but was unable to get it working. I also tried a simple port forward using iptables, but no luck there either.

Hi @jpkeenanjr,

I’ll use Nginx’s proxy as well. I usually use the following DigitalOcean article:

Can you try once again to go over it and see if it works. If it doesn’t please post your Nginx configuration file.

Another thing you can see is you Access logs to see how it redirects your connections to the server.
