I get frequent alerts from CyberSecurity Pro for Mac, for inbound traffic, which I am guessing to be inter-Apple device communication. It seems to happen when my iPhone or another Mac of mine gets near. The origin port varies - they are high ports. The destination port is TCP 64456. The source address is given in IPV6, which I cannot find on the iPhone. It is really frustrating. I started noticing that this was happening and was sure that it was inter-Apple communication. I tried saving a rule to allow it, but the source address and port are changing. Does anyone have any information that would shed light on this?
