State of Peer-to-Peer(P2P) Communication Across Network Address Translators(NATs)
This memo documents the various methods known to be in use by the peer-to-peer (P2P) applications for communication in the presence of Network Address Translators (NATs) at the current time. This memo covers NAT traversal approaches used by both TCP and UDP based applications. This memo is not an endorsement of the methods described, but merely an attempt to capture them in a document.
