Hi,

I've got the folowing configuration:

A 2011UAS-2HnD and on ether1 a connection to a 912UAG-5HPnD with VLAN tagging.

On ether2 is my internet connection. (if you ask why not on ether1, ether1 use to be my old internet connection).

ether3 is my master port for ether4 and ether5.
ether3 connects to another (dumb) switch, which connects to my notebook.
ether4 connects to my Nas
ether5 to a 750GL, which is not important for this issue.

Now the weird thing, if I'm connected to my 912UAG-5HPnD by WiFi, I'm able to use the internet connection, but I can't connect to my NAS.
I can access the webgui.

But from my notebook, which is behind ether3, I can't connect to the webgui (no ping repsonse either) of 912UAG-5HPnD but I can connec to my NAS.

I can't find out what's going wrong.

Here some parts of my config.

Any Ideas?
