I also ran into the same problem, after running a Tor intermediary relay for about half a year. Many sites block Tor exit relays, as they are pose as the origin for the sometimes harmful traffic being routed out from the network. However, running a Tor intermediary relay only sends traffic in between Tor relays and never out to the Internet. Therefore I'm kind of surprised that Apple (or Akamai or whatever service they are using) block such relays.

When using Tor as a user, ie browsing the Internet using Tor, I can turn it on and off depending on which site I'm visiting. At home, I run a Tor intermediary router to help route traffic within the Tor network, but I allow no traffic to exit from Tor to the Internet from my home IP and it's generally discouraged to do it like that, and let people and organizations who have dedicated IP:s use them for Tor relays without mixing them with other services.

The habit of blocking intermediary Tor routers and not only the Exit routers is quite serious. It's one thing if a small insignificant site does it - another thing when Akamai does it.

I really wonder that their reason for doing so is other than paranoia and FUD.

Open network system preferences. Select your interface either ethernet or Wi-Fi. Click the advanced button.

Select the DNS tab, note the numbers that are listed there and post them here

Thomas I changed the DNS entries as suggested in the modem router and in one of the MacBooks. I did it both separately and together. The problem still exists using opendns and Google DNS entries.

Yes Barney, all devices are able to connect to apple support and discussions if I use them on a different network.
