Using the router only, what categories can I block without breaking gameplay/comms? Trying to block anything related to adult content.  I understand it can slip in different ways (e.g. someone sharing it with my son).  These are the categories I have not checked yet: Download, Online Communication, Social Network and Games.  I'm thinking of trying them one by one.  It's just hard to understand what's behind those categories (e.g is Social Network specific to PC/phone apps?  Are Downloads required to get updates on the Xbox?).  I'm trying not to mess with the Xbox itself (though I understand that's an option).  Thank you
