Cannot access ShareSpace drive from Internet

I’ve trying to connect to my ShareSpace drive through http and ftp, but nothing works.  I can connect from my LAN, but when I try from WAN (both via Firefox and via IE), I get an error message.  I’ve tried using different ports for port forwarding, but itdidn’t help.  I’ve also turned off the firewall. Any other idea?

Thanks 

Sounds like your ISP is blocking port 20/21 and 80. Is there anyway to confirm?

I also tried other ports, e.g. 8000, 8001 - didn’t work either.  I assume it’s something else.

can u please connect to your ftp server from your LAN, and get the welcome message? I have a feeling it is using passive mode. As you might have already known, passive mode involves some other random ports. I am looking for something like this:

Command:    PASV
Response:    227 Entering Passive Mode (192,168,1,4,19,164)

It would be better if you could also get the welcome message when connecting from the internet.

Here is the welcome message when connecting from my LAN:

As expected, it is using passive mode:

Command:    PASV
Response:    227 Entering Passive Mode (192,168,1,9,19,142)

The response shows that, for this session, the server is listening on port (19*256)+142 = 5006 for data chanel. If this port is not properly configured on your router/proxy, you will not be able to make connection from outside.

My suggestions is to open a range of ports (5000 - 6000 maybe?).
