Bing Maps in SSRS behind proxy

Hi guys,

This is in regards to showing Bing maps in SSRS 2008 R2 behind a proxy. The server in question does not have access to DNS so I have entered a hosts entry for dev.virtualearth.net and also set the web.config file to use the proxy. The map is now displaying a 404 for each tile rather than cannot access dev.virtualearth.net. Please can you advise what other changes I would need to make to get this working.

Thanks,

Richard
