I am unable to get my Airplay (bonjour) features to work with my apple products and Denon receiver. I have seen the older posts and tried many different approaches with my Actiontec mi424wr router. I have tried (unsuccessfuly) to open the various ports Apple recommends for Airplay, I tried to disable IGMP proxy as many have suggested, among other things. Has anyone had this issue recently? Please let me know if you have had any issues (or not!) and what you did to remedy them. Help please!
