Problem in setting up NAS200 as web server

Question

Hi, I have no idea why i unable to make my NAS200 up as my web server
1st. i set up an account and domain name with tzo.
2nd, i port forward nas200 for port 80 and 21 in my router, which the 2 port is the dfault port that i use in my router setting.
3rd, to double check whether the port is open correctly, i go to www.canyouseeme.org to test the port see if the port is open. Both port showed successfully with my own WAN ip.
Then  i type in my WAN ip into browser and nothing is pop out. If this is fail, no need to talk about the TZO stuff right since TZO domain is just a shielf to protect my WAN IP.
Any idea? I doubt whether this NAS200 got problem....

Depending on your router, you may not be able to reach a device on your LAN by using the WAN address. It may be possible to change your router settings to fix this. As soon as your router will route requests to port 80 of your public address to your NAS, regardless of whether the request comes from the LAN or the WAN, you should be good to go on the web interface.
The FTP connection is a whole different story though. The FTP protocol is old and a little weird, because after the client opens a connection to the server (for commands), the server has to open a secondary connection to the client for data. This is largely incompatible with the NAT translation that your router does. Most routers are smart enough nowadays to translate the commands when the FTP client is on the LAN and the server is on the WAN but not the other way around (there are some exceptions).
Apart from all this, the FTP protocol is insecure, and any neighbor can listen in on your FTP traffic and catch all your passwords and files.
Instead of FTP, I recommend using my firmware (see link in signature) which will let you use the SCP protocol over SSH; you will need to open port 22 instead of 21 (and 20) and you will be able to connect to the NAS via a secure connection to download as well as upload files (the HTTP interface will only let you download files from the NAS200).
For more information, see the links in my signature.

Frequent NAS200 Answers:
1. DISABLE the "convert failed logins to guest logins" option to fix permission problems.
2. NEVER insert or remove hard disks while the power is on. NAS200 doesn't support hot swapping.
3. ALWAYS use the power button to turn the NAS200 off, don't just unplug it.
4. Don't trust RAID. Make BACKUPS!
5. To ACCESS the disks directly, you will need ext2 and/or XFS file systems. I recommend using SystemRescueCD.
6. Disks will get HOT with standard fan, use "green" disks or consider replacing the fan.
7. FTP server is insecure and doesn't work behind a NAT router. Use my firmware and SCP instead.
8. MY FIRMWARE supports SSH shell prompt and SCP for secure file access, and allows running other software.
