How to set up a remote ftp connection?

Question

Computer networks

I have ftp on my raspberry pi. Router tp-link archer c6. I want to have access to ftp from anywhere, not just from the local area. I do not want to connect a static address, but the router supports DDNS (if it helps). What do I need to do for this?

Answer 1

The IP address must be white. Dynamic or static, it doesn't matter. On the router, port forwarding or DMZ to the server IP.

Answer 2

Domain?

Answer 3

configure ddns, it often takes time for dns to "announce". check with nslkookup that your name expands to your ip.
in the router settings, set permissions for access to ftp from the Internet / wan or something like that.
try to access your DDNS address via ftp client from local computer.
try to access your DDNS address via ftp client from another computer (which is not connected to the internet through this router).
If everything works, then everything works.
