External FTP & web access

[fahl]

New DSm 7 user,How can i set up external access to Ftp & sahared folders please.

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

So you have port forward in place? Firewall problem maybe? What kind of error are you getting? Have you set your account permissions to use FTP?

 

[fredbert]

For FTP, if using active mode, does your firewall open the ad-hoc data session ports when it sees the initial control connection?

Getting

[12:10:50] Winsock 2.2 -- OpenSSL 1.1.0e  16 Feb 2017
[12:11:54] [R] Unable to resolve host: ftp://QuickConnect.to/******

Router is forwarded.

Have you set your account permissions to use FTP?

Not sure how to do that?

 

[Rusty]

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

 

[Rusty]

firewall disabled

When you say FW disabled, you mean the one on your NAS correct? Or both NAS and router as well?

 

[fahl]

Tried disabling Windows firewall,Nas firewall & router firewall,still the same.
getting this on Remote connection setup,This address connects to Nas fine.

 

[Rusty]

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

what about if you try and connect using your current public ip address? Does that work?

 

[fahl]

No it doesnt

 

[Rusty]

well in that case its still a port problem, nothing much it can be if your nas in general is accessible from the outside

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.

You can if your router support it. So it’s not impossible in general
