Anyone any good with Feedburner?

My blog has been added to someones feed which is great – but – if you click the title of the blog it is always broken.

This is the link that is broken:

http://feedproxy.google.com/~r/SecurityBloggersNetwork/~3/e67RnOFX8CE/

The feed is fine from the actual feed itself its just when you click the blog post from the feed BACK to my site it is broken.

Does my wordpress blog need an app or widget to “accept” the incoming feed?

Thanks
