Installing RN314 - Device not detected

The Inteno I have is a much older model, for which I can't find much official information (Inteno x6545, also branded as Xavi x6545). I don't seem to be able to find a way of getting at its settings though, and an old post in a forum says that it's most likely a router which is in bridge mode. I'm trying to find out from my IPS how I would go about accessing its settings.

I plugged in the Belkin now, and my setup goes: Fiber connection -> Gateway -> Belkin router -> (NAS & PC). RAIDar can see my NAS, but ReadyCloud can't, and I can't access the NAS IP-address through my browser.

IPConfig on my PC gives me this info:
IPv4 Address. . . . . . . . . . . : 192.168.2.4 (Preferred)
Subnet Mask . . . . . . . . . . . : 255.255.255.0
DHCP enabled: Yes

Going into the settings on the Belkin router shows me:
IP Address. . . . . . . . . . . : 192.168.2.1
Subnet Mask . . . . . . . . . . . : 255.255.255.0
DHCP server: On
IP Pool Starting Address > 192.168.2.2
IP Pool Ending address > 192.168.2.100

Is there something else I should be looking for or changing?

Thanks.
