What sites the XCode access when we will publish a app

In my company, we have a stupid firewall. It block all itunes.apple.com sites and to publish an app, we have to use our internet. To publish a app, we have to go in this screen in Organizer and press "Share"

Was asked me: what things you have to unblock to publish an app? With my limited knowledge I use the Wireshark and discovery that the program first access the site:

http://contentdelivery.itunes.apple.com:443

But and after, there are a special port, or a magic thing that the firewall can block? Or it have to unblo开发者_运维百科ck only site with itunes.apple.com for http and https? I really don't know find it :(

I'd try something like Little Snitch to find out, it will pop up a box every time a program tries to access something on the internet - giving you the address and port number.

I find it pretty useful for this and testing connectivity issues in debugging.
