USB Sharing type FTP (via internet) suddenly stopped working

[cm55]

Hi,

I have been sucessfully using the FTP via internet setting until one day it just stopped working.

After extensive debugging I simply cannot explain it!

The URL is ... ftp://myrs.mynetgear.com:1921/shares/

It just won't connect, times out on connection, nothing has changed.  All the other sharing options work, including FTP from inside the network!

I have tried it with the direct IP and with port 21, and every security setting there is and I still get nothing.

Please help as the only option I have left is a warranty claim which seems silly given it's a software problem!

It's OK I found the problem somewhere I wasn't expecting - my ISP implemented CGNAT 😞

Try a factory reset and reconfigure from scratch.

Done, made no difference!

Is there any chance that your public IP address has changed?

[cm55]

No, just double checked and still the same, to confirm this does not work...

ftp://188.172.150.99:1921

Where it is set up as so...

Hi cm55,

Can you try to access the HTTPS(via internet) if you can access it or not. If not, try reloading the previous firmware, reset and reconfigure.

Hi James

I also cannot access the HTTPS over internet.

I reverted the firmware back and the same problem exisits, have tried every possible way of accessing, e.g. from other networks, using direct IP.  Nothing works 😞
