iTouch Remote and McAfee Firewall conflict

I have the most recent version of the Remote app and iTunes. For a while I had the problem where I couldn't add my library to Remote. I made iTunes forget all remotes, but that didn't work. As I was seriously trying hard to figure this out, I noticed that McAfee was blocking the connection because it worked fine after I turned off the firewall. For obvious reasons, I don't want to keep my firewall off. I tried different settings and exceptions for the firewall, but nothing is working so far. What port(s) should I unblock to allow the connection?
