* [0] is the normal/default port, usually 9993 |
|
* [1] is a port derived from our ZeroTier address |
|
* [2] is a port computed from the normal/default for use with uPnP/NAT-PMP mappings |
|

* [2] exists because on some gateways trying to do regular NAT-t interferes |
|
* destructively with uPnP port mapping behavior in very weird buggy ways. |

* It's only used if uPnP/NAT-PMP is enabled in this build. |
