Abstract
In a method of Local Peer to Peer Direct Connection in NAT and overlay network. A request is received from a first peer at a relay gateway to establish a direct connection with a second peer. The first peer and the second peer are located behind a NAT firewall. An authentication request is relayed from the first peer at the relay gateway. The authentication request is forwarded from the relay gateway to the second peer. Upon performing authentication at the second peer, an authentication response is received at the relay gateway. The authentication response is received from the relay gateway at the first peer. An internal route propagation is performed from the second peer to the first peer via the relay gateway. A Local Peer to Peer Direct Connection is established between the first peer and the second peer for packet flow through the direct connection.
