iMessage / iCloud via SSH Port forward to get through firewall
Solution 1:
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
