What FTP client are you using?

Note that with passive FTP ports, the masquerading can be set up for either inside the router or outside the router, but not both. However, if you set up the NAS for inside-the-router (the default),the FileZilla client will work properly outside-the-router as well- it detects and works around the issue.

I tried using Filezilla as a client. Here is the error.

Your FileZilla client is not using passive FTP. If you look under "settings" is the transfer mode set to Passive (recommended)? You can also set this for each FTP server in the site manager transfer settings.

It fails in passive mode.

Ok. And the passive ports configured on the NAS are all forwarded to the NAS in the router? Also, does it work normally inside the firewall (in passive mode)?

All ports in the router are forwarded to the NAS.
I confirmed that the ports are open.
It does work correctly inside the firewall.

I think the problem is that your internal IP address looks routeable to FileZilla (173.xxx.xxx.xxx)

This is what I see(ftp over tls)...

Where did you get the SFTP app for the NAS

It's not SFTP - it is FTP over TLS. The normal NAS firmware supports it.

Do you know if there is an app for the nas to do sftp?
