I recently upgraded my linksys E1000 to:
linksys E4200 ( i needed gb port)
in my QNAP i can scan for upnp routers to set the forwarding port automaticly.
But it keeps telling my, it can't find an upnp router on my network.
my E1000 was found without any problem!
If i open the port manually for example FTP 21
I cannot get acces from the internet, it keeps telling me its closed.
i forwarded it to the right ip. an clicked to apply
I find this very strange.
The website from QNAP says the E4200 is certified for upnp
So tho sum up:
I cannot acces my NAS from the internet.
modem/router (ZIGGO) --- Linksys E4200 ---- QNAP 412 turbo
linksys E4200 firmware 10.04

You can try the following combination of settings:-
A] With the help of Cisco Connect Software (if at all you have installed the router with the help of this software)
1] Open the software and go to the option which says "Router Settings"
2] Then click on the option which says "Advanced Settings" which will take you to the router's configuration page.
3] Then click on Security tab disable SPI Firewall Protection, uncheck Filter Anonymous Internet Requests...
B] If you haven't installed Cisco Connect then you can log on to the router's user interface using it's default IP address in the browser which is 192.168.1.1 and type in 'admin' as the password leaving the user name field blank. This will take you to the router's web interface and then follow steps as mentioned above to make the changes.

I also have the same problem.
Can you tell me how you open the ports manually?
Thanks in advnace.
1. Access the setup page of your router
-to do this: Open a browser, type in 192.168.1.1 on the address bar, type admin for the password (once you're asked to login)
2. Click on the Application and Gaming tab
3. You can select either Port Range Triggering or Port Range Forwarding on the subtabs
4. Open the ports you want to open on the page

Thanks that worked perfectly.
I also open a ticket in QNAP and they sent me detailed instructions on the ports that needed to be open.
Now I'm up and running.

I have the same problem with my E4200.
I would be grateful if you could kindly post the QNAP's detailed instructions on the ports and port forwarding.
+ what is the difference between port triggering / port range forwarding ?

Port Forwarding sets up public services on your network such as web servers, FTP servers, e-mail servers, or other specialized Internet applications. When users send this type of request to your network via the Internet, the router will forward these requests to the appropriate computer. This is configured on a router if you are using a server computer or a game server.
There are two types of Port Forwarding:
1. Single Port Forwarding
This type allows you to set up public services one by one on your network such as web servers, FTP servers, email servers, or other specialized Internet applications. Before using forwarding, you should assign static IP addresses to the designated computers.
NOTE: Specialized Internet applications are any applications that use Internet access to perform functions such as videoconferencing or online gaming. Some Internet applications may not require any forwarding.
2. Port Range Forwarding
This type allows you to set up public services in a group which means a range of ports, for example from 20 ~ 25. Certain applications may require opening specific ports in order for it to function correctly. Examples of these applications include servers and certain online games. When a request for a certain port comes in from the Internet, the router will route the data to the computer you specify.
NOTE: Due to security concerns, you may want to limit port forwarding to only those ports you are using, and uncheck the Enable checkbox after you are finished.
Port Triggering sets up the router so that computers will be able to access public services outside the network or on the Internet, such as web servers, FTP servers, email servers, game servers or other Internet applications.
