making sure your port is open to all external IP addresses

[boco]

Correct, port forwards are done in the router. Needs to be the complete range.
Complete range must also be opened in the server's firewall.

[pythonprogram]

So, I've still been working hard at this and I was able to get into my router and set the port range in the port forwarding along with setting it to port 21 for this computer that I am using. When I tried it out in the FTP tester I received the following message:

Error: Server returned unroutable private IP address in PASV reply

Make sure the server is configured to allow passive mode connections.
If the server is behind a NAT router, make sure the server knows its external IP address.
The range of ports used for passive mode must be opened in all involved firewalls.
The range of ports used for passive mode must be forwarded by all involved NAT routers.
Try uninstalling all firewalls and plug your computer directly into your modem, thus bypassing the router.

Some help would be greatly appreciated. I think I am getting close to getting this completed and with help I know it can be done. Thank you

When it connects I then receive the following message:

There should be more on this line, never modify logs. According to the test, you didn't tell the Server your public IP, it returns the private one which is unusable in this context.

That was the rest of the line. Thank you for your help.

I thought I was using my public IP address? I went to google and typed in what is my IP address. I then used that address (IPV4) to do the log in. At this point I am not really sure what is going on. Please help.

Please study our Network Configuration guide for an in-depth explanation, it will all become clear.

[pythonprogram]

Thanks for the reply @Botg

I've read it about 5 times..look at several youtube videos and I've tried possible solutions with ChatGPT. In the Network configuration guide it even says the setting up and testing FTP Server instructions are outdated.

At this point I just do not know. I've been at it for weeks with this.

[botg]

In the passive mode settings of the server you need to tell it your public IP address.

[pythonprogram]

I received the following message:

"Your server is working and assorted routers/firewalls have been correctly configured for explicit FTP over TLS as performed by this test. However there have been warnings about compatibility issues, not all users will be able to use your server.
For maximum compatibility, consider resolving these warnings."

It seems as though I am set up. Thank you!! I appreciate you @botg and boco for your help and patience that you've had with me. This was really difficult for me to understand because I am new to this. I do not know anything about how this stuff works.
