Help needed to configure FTP with DynDNS

[leo1986pc]

Hi all,
i've just registrated a host on dyndns.org and i've tried to configure the service on NAS4FREE.
My configuration works in my network but doesn't work if I try to reach my FTP from another network so I think there's a problem with the configuration of dyndns.org.

These are my settings:

Dynamic DNS: Enabled
Provider: dyndns.org
Domani name: (HOSTNAME)
Username: (account on dyndns.org)
Password: (account on dyndns.org)
Update period: 120
Forced update period: 120

FTP: enabled
(default values)

I think that the problem is in the confinguration of the hostname in dyndns.org because I've setted the IP Address of my PC not the pubblic IP of NAS4FREE but I don't know it.

Can someone help me?

Did you set port forwarding at your router?
BTW, it's not recommended better use VPN

Did you set port forwarding at your router?

Yes, router forwarded. TCP 20/21 on NAS's IP

you are aware that ftp is not encrypted?

the passwords for the login are transfered in plain text across the internet.
anyone in between can listen in on the communication and see the password.

Security is not my problem now.

To check if it is a matter of DyDNS, just try to access it with your routers IP you got from your ISP

Yes, I can access by my IP

What error do you get when you enter
ftp://yourname.dyndns.org just in your webbrowser ?

It doesn't load the page and the connection goes to time out

check your external ip
http://www.ping.eu/nslookup/
and see which ip your dyndns returns and if its the same

do a telnet connection on the port and see if you can get a connection.

I'm not able at all with telnet but if I digit

Code: Select all

telnet 192.168.1.10 21

the system answers

Code: Select all

220 ProFTPD 1.3.4d Server (nas4free FTP Server) [::ffff:192.168.1.10]

do that from the outside.
not internally

I've just called my ISP and they will open a service on my router in the next 24h.

See last 3 raws of this topic https://trac.transmissionbt.com/wiki/PortClosed

I'll keep you updated!

why does your isp have access to your router?
i would not want my isp to change any settings on my router.

Me too.
I don't how it works but in Italy we have a "master ISP" (Telecom) and others (like Fastweb, TeleTu, Vodafone, ecc...) that are cheaper.
Others buy from Telecom some public IP and they NAT's the traffic to you.
So you can forward ports on your router but they have to forward that ports on their "master router" for you.
Now they will open a configuration page for me on their "master router" and I'll be able to forward ports to my liking.
But I repeat that I don't know how it really works.
