# magic-wormhole-transit-relay [![Build Status](https://travis-ci.org/warner/magic-wormhole-transit-relay.svg?branch=master)](https://travis-ci.org/warner/magic-wormhole-transit-relay) [![codecov.io](https://codecov.io/github/warner/magic-wormhole-transit-relay/coverage.svg?branch=master)](https://codecov.io/github/warner/magic-wormhole-transit-relay?branch=master) Transit Relay server for Magic-Wormhole This repository implements the Magic-Wormhole "Transit Relay", a server that helps clients establish bulk-data transit connections even when both are behind NAT boxes. Each side makes a TCP connection to this server and presents a handshake. Two connections with identical handshakes are glued together, allowing them to pretend they have a direct connection. This server used to be included in the magic-wormhole repository, but was split out into a separate repo to aid deployment and development. See docs/running.md for instructions to launch the server.
