Relay nodes

[kehiy]

In this part of libp2p docs:

https://docs.libp2p.io/concepts/nat/circuit-relay/#process

The A node is already behind a NAT, but how does Relay R dail it when node B tells wants a connection to node A?

It doesn't :)

A dials the relay and makes a "reservation" and keeps the connection alive.

R can then at any point establish a stream to it.
