Apple TCP Information

[JATSO]

We have been having problems connecting to Apple for updates etc, so today we had a very helpful support rep from Apple help get our iPad's back online.

 

He sent me over a link to TCP and UDP ports used by Apple https://support.apple.com/en-gb/HT202944 and also in the was was a bit more information about our issue.

 

The context of the email is below.

 

A very helpful chap.

 

It's good to share

 

As I mentioned in the call all our server run on an IP with 17.x.x.x.

We own the 17-series so anything coming from an IP starting with 17 will be from/to an official Apple.

 

So if possible, you can open 17.0.0.0/8 in your firewall.

 

Otherwise some ports and servers are mentioned here, this is more for iTunes and App Store service though:

https://support.apple.com/en-ie/HT201999

 

I know albert.apple.com is used for activation of devices though, possible that might be the issue.

 

All our ports are mentioned here, you can search this page for iCloud:

https://support.apple.com/en-gb/HT202944

 

I would also recommend trying to open iCloud.com.
