Ring and OpenDNS


For those familiar with OpenDNS:

I use OpenDNS for web filtering. I have to have the P2P/File Sharing category filtered. Unfortunately, however, Ring live feed stops working when this is filtered. Of course, when I uncheck the category, it starts working again. Does anyone else familiar with OpenDNS know which domain we have to allow to have live feed accessible again while using OpenDNS AND having P2P/File Sharing filtered?
