ReadyNas DNS problem

Well, there is another router (ADSL-modem) in front of the FVS338. That's where the 192.169.1.254 adress is originating from. The ProSafe is the 192.169.0.1. The reason I'm using 192.169 is pure inheritance. I doubt however that that would be the reason for why the ReadyNas is not resolving or even being able to ping adresses outside the Network.

Adresses resolved by other computers, also behind the nat, (for instance www.google.com or ftp.sunet.se) will not work on the ReadyNas, but works perfectly on other computers behind the NAT.

Pinging from the ReadyNas:
ultra:~# ping 194.71.11.69
PING 194.71.11.69 (194.71.11.69) 56(84) bytes of data.
