<s>[INST] How to access the local Django webserver from outside world I followed the instructions here to run Django using the built-in webserver and was able to successfully run it using python manage.py runserver.  If I access 127.0.0.1:port locally from the webserver, I get the Django page indicating it worked.
I realize the Django webserver is not a production server, but it's important for me for testing purposes to be able to access it from the outside world -- i.e. not from a web browser on the server, but from a different computer.  
I tried:
http://mywebserver:port_django_runs_on

but it did not work.  I also tried using the IP instead (based on ifconfig) to access:
http://myipaddress:port_django_runs_on 

which did not work either.
The web server is running so it must be accessible from the outside, I'm just not sure how.  I am running Linux with Apache, though I have not configured Django with Apache.
Any ideas on how to do this? 
 [/INST] You have to run the development server such that it listens on the interface to your network.
E.g.
python manage.py runserver 0.0.0.0:8000

listens on every interface on port 8000.
It doesn't matter whether you access the webserver with the IP or the hostname. I guess you are still in your own LAN.
If you really want to access the server from outside, you also have to configure your router to forward port e.g. 8000 to your server.

Check your firewall on your server whether incoming connections to the port in use are allowed!
Assuming you can access your Apache server from the outside successfully, you can also try this:

Stop the Apache server, so that port 80 is free.
Start the development server with sudo python manage.py runserver 0.0.0.0:80
