MACHINE1: Run Node-red. Access it via 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

thank you its seems easy as you say.
can you please explain how open port 1880 on rasberry Pi 3.

i tried but didn't work.
firewall is off in both MACHINE.

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

11

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

12

windows 7 OS in both machine.
i entered in machine2 : http://IP of machine (node-red running):1880

13

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

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

Thank you. I could access Node Red UI using my phone with port 1880 (Since I was on a LAN )

19 
sudo ufw allow 1880

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