I am getting into web development for the first time and my purpose now is to test my website from external devices.
I have a mobile router. What I would like to do is to create a home network in such a way that all the devices connected to the router (wirelessly) would be part of the same network, to (e.g.) be able to see the prototype of the website I am building on my laptop through my smartphone. Is this possible?
I am on Ubuntu 16.04, and I personally don't have great experience with networking stuff, so I hope my question is clear.
EDIT 1
Just to clarify a bit what I would like to do... I am following this tutorial on setting up a webserver using Raspberry and Flask. In step 7 ("Browsing on other devices"), it reads Since we used host='0.0.0.0', on the app.run line, the web server is accessible to any device on the same network, including other computers, tablets, and smartphones.(...) Open up a web browser on the other device and enter the Raspberry Pi's IP address into the address bar with :5000 on the end e.g. http://192.168.1.3:5000/.
Of course, I use the laptop IP instead of the Raspberry one. However, the content of the page is not showed from my smartphone.
The router is a Vodafone R216-Z 4G WiFi (I found some specs at this page).
