Linksys Wireless Router :: Upnp E4200 Not Working With QNAP 412 Turbo?

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. The website from QNAP says the E4200 is certified for upnp

So tho sum up: I cannot acces my NAS from the internet.

My setup:

Modem/router (ZIGGO) --- Linksys E4200 ---- QNAP 412 turbo

Linksys E4200 firmware 10.04
