External access

[bob gailer]

I am running a the django server, listening at port 8000. I can access
the server using localhost. When I try using my external ip address I
get "The server at 24.211.133.163 is taking too long to respond." I have
port 8000 forwarded to my server computer in my router. What more do I
need to do?

[GMail]

Hi! Seems like port forwarding doesn't work correctly. Do you have any other ports forwarded (like ssh or ftp)? If so, do they work as expected?

What is this command's output:
telnet <external_ip> 8000

Is the port open on the firewall? What OS are you on?

[Andreas Kuhne]

Do you have "ALLOWED_HOSTS" correclty configured in django settings?

By default, runserver only binds to 127.0.0.1:8000, which makes it
only accessible over the loopback interface. If you want to make it
accessible from all interfaces, try starting it up like this:

./manage.py runserver 0.0.0.0:8000

Good luck,

Michal

[bob gailer]

How would I determine that?

Windows 10.

Sorry but I'm running Windows 10 which does not recognize "telnet"

Sorry, I do not know anything about Windows.I only work with Linux.

Thanks - was not aware of that. Now it looks like:
ALLOWED_HOSTS = ['209.216.2.211', '209.216.15.70', '24.211.133.163']
The last one is my external ip

Adding the ip addresses did not fix the problem.

Wow... Indeed, in Windows telnet is disabled by default. Here's how you can enable it (first link on Google): https://www.rootusers.com/how-to-enable-the-telnet-client-in-windows-10/

I believe the problem is (how somebody already mentioned earlier) your port is inaccessible from external network or server is only serving on lo (loopback interface, also was mentioned earlier). You could easily test both cases with telnet. And I forgot to mention, that you should probably run telnet on separate machine (not the one serving Django), since you have no problem accessing your server locally.

How would I do that?

I have no machines that are not on my lan.

You forgot to specify port, command should be 'telnet 24.211.133.163 8000' (if you're running Django on different port, change 8000 to your port).

> How would I do that?

I believe it was mentioned earlier in this thread: 'python manage.py runserver 0.0.0.0:8000' or 'python manage.py runserver [::]:8000' for ipv6 (probably not your case though).

> I have no machines that are not on my lan.

I've actually tried to connect to your server from my machine:
% telnet 24.211.133.163 80
Trying 24.211.133.163...
telnet: Unable to connect to remote host: Connection refused
% telnet 24.211.133.163 443
Trying 24.211.133.163...
telnet: Unable to connect to remote host: Connection refused
% telnet 24.211.133.163 8000
Trying 24.211.133.163...
<nothing happens>

It seems like your router or Windows firewall (or it may be any antivirus software with embedded firewall installed on your server) is rejecting connections to 8000 port. Unfortunately, I can't help you with any Windows-related issues.

I could try to help you with your router settings, but I think, since this is not about Django anymore, this discussion should not take place in django-users@. Feel free to contact me personally though.

I don't totally understand how it works under the hood, but using the answer Michal Petrucha provided earlier has worked for me in this situation independent of the OS and any router settings.

Run the server using:

python manage.py runserver 0.0.0.0:8000

You'll be able to get to at http://<your ip>:8000 from the machine running the server. With most default router configurations you should also be able to access 

it from any computer on your LAN at the same url.

If you need to access it outside your LAN you'll have to delve into port forwarding

Here is an update on my situation.

Windows firewall - I setup in and outbound rules for port 8000 (UDP and TCP)
Router - I set up port forwarding for port 8000 (UDP and TCP)
Using example code in the socket module documentation I ram
socket_client and socket_server on my local machine with the port=8000
and host=my external IP . It worked just fine.
When I run the django server instead of the socket server and attempt
browser access thru my external IP I get a timeout.
Nothing appears on the console running the server.

So something is different . Any ideas?

I presume that the browser - django server communication at most uses
TCP and/or UDP.

Any ideas are welcome.

[Antonis Christofides]

When you reply to a message please include the previous emails of that thread.
People who read this list on a mail client might have deleted them and they are
probably not going to look them up elsewhere in order to remember what the
problem was.

So, how are you running the Django development server? "python manage.py
runserver 0.0.0.0:8000"?

[Luis Zárate]

First, start testing you machine port is available in your local network run

python manage.py runserver 0.0.0.0:8000

In other machine in the same network test it
Suppose your django machine has  internal ip address 192.168.1.100, then try to access 192.168.1.100:8000 from your web browser in the other machine.

If works then your problem is the NAT on router, if don't your problem is your firewall in the machine, so try to shutdown firewall and try again if works then test external IP if works then configure your firewall for incoming traffic and start it again.
