Can't access amazon website via OpenVPN...

[matd]

Hi,

I've setup OpenVPN on my QNAP NAS and i'm using OpenVPN for Windows on a remote PC. I can access all of my LAN resources via the NAS but for some reason i can't access amazon.co.uk, all other websites appear to work ok. I've changed the DNS servers on the NAS to Google but it just times out and can't load the page whenever i try and access amazon.co.uk. If i disconnect the OpenVPN connection and refresh my browser amazon loads up fine. Also no problem accecssing Amazon from the LAN where the NAS i located...

Any ideas please?
