Netgear DGN2000 - Repeater Will Not See NAS?

I have a Netgear DGN2000 which I use as my main router/modem. This is ADSL and works perfectly.I have added a Belkin F5Z0102 UK G Wireless ADSL Modem Router as a wireless range extender.It is connected to the Netgear via homeplug and works fine for connecting to the internet on all my gadgetry (ie internet radio, netbooks and mobile phone) via wireless and wired.My problem is when the internet radio and music player on my phone try to connect to the NAS, connected via ethernet cable to the Netgear router.I can connect to the NAS via it's IP address directly but it will not be recognised by the software on the radio or phone.However,if I connect to the Netgear router (first), it recognises it straight away.

To allow access, do I need to change the settings of the router to point to the other router in any particular way?I have specified the second router as 192.168.0.2 and this points back to the Netgear router in the settings. The SSID is different to the first because if I put it as the same, the router gets confused and I lose all connectivity. I have also disabled the DHCP settings ont he second router. Forgot to mention that it is set up as a 1483 Bridge.
