Good evening,
I purchased a NAS D-link 320.
It is completely operational in premises but I have concerns to make it accessible by the outside (essential for me!)
In premises:
Access to the administration of the NAS (port 80):OK by http: // 192.168.0.5 / Web / home.html
Access to the FTP of the NAS (port 21):Ok by ftp: // 192.168.0.5:21
By the net:
Access to the administration of the NAS (port 80): non-OK
Access to the FTP of the NAS (port 21): non-OK
I made some screens of the NAS admin:
Network

FTP

And some screens of the modem admin:
DHCP

option

redirection

firewall

I have no preferences for the addresses ips and ports, would just want that that works.
Thank you in advance for your help!
