MACHINE1: Run Node-red. Access it via [http://localhost:1880](http://localhost:1880)  
MACHINE2 Open browser. Enter http://IP\_OF\_MACHINE1:1880

where IP\_OF\_MACHINE1 == the IP address of where node-red is running.

As it WEB - the simple answer is "of course". You just need the URL.

However, if the machine where Node-RED runs is firewalled then you gotta open port 1880 on that machine

If you are running standard Raspbian and have not activated a firewall then it will already be open.

What are you entering in the browser?  
What operating systems are the two machines running.

Is that exactly what you entered or did you put an actual ip address in? If so what is that address? What did you then see in the browser?

Doing this safely and securely is not trivial.

Please see [https://github.com/node-red/cookbook.nodered.org/wiki/How-to-safely-expose-Node-RED-to-the-Internet](https://github.com/node-red/cookbook.nodered.org/wiki/How-to-safely-expose-Node-RED-to-the-Internet)

this Works perfectly just you have to have Same Internet service for all devices connected to it.

```auto
sudo ufw allow 1880

Run that command in your raspberry pi terminal in case your pi's firewall is enabled
