Port 21 will do.
Have you disable your router's 21port if it has it enabled?
You can try http://net2ftp.com/ to check your ftp from outside, since checking from inside not always work, unless you have somebody from an external network testing your ftp.

..but I also tried to make the SMS server an exposed host (Open to the internet) and that did not change anything. Could be that my internal PCs are blocked but my windows firewall allows FTP?
My PC is found at lsoathome.dyndns.org in case you want to try it out from your PC.

I tried net2ftp but could not connect

All your ports are filtered, meaning there is a firewall blocking them...
Either your port forward is not working or you might have an extra protection from your ISP through ports 0-1000.
Try port forward port 35665 to 21in your local machine and try to login from outside at
lsoathome.dyndns.org:35665

I had hooked my SMS server up to a wireless repeater - now it is attached directly to the router and teh WEB server is seen from the outside - still no luck with the FTP server

This is the result of nmap

correct!

I'm guessing all fritzbox are little bit the same, so go to
System and enable expert mode , if it's not enabled and then
Internet -> Port Forward

Have you try to restart router, just in case?
Also have you tried a higher port number as I suggest in previous posts e.g. 55000->21?

I always work in expert mode Wink

I rebooted server and router and now net2ftp connects correctly and my server is seen from the outside as well.

21/tcp open ftp vsftpd 2.0.8 or later
80/tcp open http Apache httpd 2.2.21 ((Unix) mod_ssl/2.2.21 OpenSSL/0.9.8r DAV/2 PHP/5.3. Cool

Thanks a lot for all your time, support and patience - I learned a lot!

very strange.
Today server and FTP is not available from the outside - I can ping lsoathome.dyndns.org but time out on the server as http and FTP
This is driving me crazy Mad

Port forward is enabled as I can see,but service is down unless this is not you.

I have ddclient running on the SMS server and checking with the DYNDNS homepage it updates the IP address as needed. The SMS server has a static IP address internally in order to assign open ports to it.

I did a DIG and Question/Answer gave me the external IP address

I am now using a good old Belkin router where I have opened the HTTP and FTP ports for the SMS server but the result is the same so seems the issue is in the SMS server

If server is accessible from local network, I don't think SMS has an issue, unless fail2ban ban your external visitors.
You can try to stop fail2ban or restart it and check again.

You can check
iptables -L
to see if there is something blocked.

Do you have uPnP enabled or DMZ option in your router to try it?

The problem was approximately 80 cm in front of the PC: I had opened the ports using the wrong IP address: ...102 instead of ...103 (the server has been given the iP .103 mapped with its MAC-address
