SharePoint RSS Viewer Error

Having added the SharePoint OOB RSS web part on to my site and configured it to point to a feed i received the following error in the log:

RssWebPart: Exception handed to HandleRuntimeException.HandleException System.Net.WebException: Unable to connect to the remote server

Found the solution here: http://yasirbutt.spaces.live.com/blog/cns!A8677D5751E6B4DA!1409.entry

The following needs adding to the site web.config file (at the bottom of the file):

<system.net>
<defaultProxy>
<proxy usesystemdefault = "false" proxyaddress="http://proxyservername" bypassonlocal="true" />
</defaultProxy>
</system.net>
