First, make sure that your NAS is accessible from the outside by having access via External Access options in the control panel (QC or DDNS).

Then open the FTP port (or a secure one) on your router, and finally use the client to connect via FTP to your NAS (with a valid account).
Thanks for reply.
Already done all that,can access ftp fine through local ip,but not through web address or Quickconnect name.
How can i check my Nas external ip
[12:10:50] Winsock 2.2 -- OpenSSL 1.1.0e  16 Feb 2017

Router is forwarded.
Have you set your account permissions to use FTP?
Not sure how to do that?
Not sure how to do that?
Under your account details in Control Panel, you can select apps and services that have permission (or not).

The fact that you have been unable to resolve the host, can mean that your nas is really not accessible/visible on the net as it should be. Check port forward again, and check if your firewall is not the problem (on your router and on the nas itself)
Sorry new to this,old & disabled.

Try again.

All ports are forwarded in router & have been checked by Canyouseeme.
firewall disabled.

Even tried DMZ

Ip is Virgin media static running through TP-Link router

All i want to do is access DS414 via Ftp from external address.Local works fine.

Ftp client works on port 21 on my other external addresses,just not Synology.

It seems that anything external is blocked by DSM7.

Tried using Quick connect using this format "myid.synology.me" which wont connect,

Also No-Ip ddns,This connects to NAS,as it should,but wont work with ftp

You mean that you're running FTP servers on other devices behind your firewall/router? And that you've an Internet IP subnet assigned to map to these devices?

How have you configured the firewall policy on the router to allow these FTP servers to work successfully?

Here's a well written piece on active and passive mode in FTP.

Within Synology FTP service you will have a port range assigned for listening for data connection sessions. Have you opened the router's firewall and NAT to enable these connections?

Many Thanks for help but think this is all sorted.
Hadn't realise that you cant access external content from local pc.
