Overview ¶
The NAT package is responsible for
- obtaining a pair of public IP and port that can be announced to external nodes and can be used for sending traffic to this node.
- keep that NAT traversal mechanism active, either by sending keepalives or by notifying the corresponding service about our interest in keeping it active.
