iMessage / iCloud via SSH Port forward to get through firewall What ports does iCloud and iMessage use and is it possible to use SSH port forwarding via  a proxy to use them on a network that blocks the services?
According to: http://support.apple.com/en-us/HT202078

| Ports                     |FaceTime | iMessage|
| 80 (TCP)                  |    ✓    |    ✓    |
| 443 (TCP)                 |    ✓    |    ✓    |
| 3478 through 3497 (UDP)   |    ✓    |    -    |
| 5223 (TCP)                |    ✓    |    ✓    |
| 16384 through 16387 (UDP) |    ✓    |    -    |
| 16393 through 16402 (UDP) |    ✓    |    -    |


Which means 80, 443, and 5223



That being said I have YET to actually tunnel iMessage correctly
