This information is great. I used the link to get into the IGMP proxy settings and disabled it. This fix worked for a few hours and then stopped. I checked to make sure the proxy was still disabled and it was. I could not do any bonjour type service(ie screen sharing from MacBook Pro to iMac, file sharing, wifi sync from ios devices, etc). I contacted verizon and they said that they have a memo that states that there is a known flaw in the Apple Bonjour Services software, apple is aware and is working in a fix. The memo was dated 10/22/12. Any thoughts? Ideas?
