VPNRelay object holds information about each
relay you created. Relays are used to pipe/forward/relay/redirect UDP
packets from one peer to another. It are usually used when (for whatever
reason) peers are unable to establish direct connection. In such cases,
you should create new relay on some Port, and you should pass IP address
and Port specified by the relay to their Connect method. Timing is
irrelevant here.
Once users are able to connect to your relay,
RelayConnected
event will be fired where you can check if peers are ones you expected
them to be.
