Apple has posted a new support document explaining how to configure a firewall or security software to enable iPhone 4 FaceTime video chats over Wi-Fi. The document claims that while FaceTime will “just work” on most Wi-Fi networks, the feature may fail on some networks protected by a firewall. According to the document, port forwarding must be enabled for ports 53, 80, 443, 4080, 5223, and 16393-16472 (UDP) for FaceTime to function correctly on firewall-protected networks. For all other Wi-Fi related issues, Apple refers users to its general Wi-Fi troubleshooting document.
