Enum Transport 

pub enum Transport {
    Direct,
    RelayOnly,
}

How the endpoint puts itself on the network.

The distinction only matters on a machine where the user cannot answer a firewall prompt — see Transport::RelayOnly.

Variants

Direct

Bind UDP on every interface and ask the gateway for a port mapping. Hole punching gets a direct path when it can, and the relay picks up the rest.

RelayOnly

Bind no UDP socket and skip the gateway probe, so everything rides the relay over an outbound connection.

Slower — every byte takes the long way round — but nothing ever listens on a real interface. That is what a machine without administrator rights needs: binding 0.0.0.0 and the UPnP discovery multicast are each enough to make Windows raise a firewall prompt that only an administrator can answer, and one that is dismissed comes straight back on the next start.
