gamebridge is a generalized tool that listens for user-configurable traffic on a local network, (usually broadcast UDP data), then transports that data to user-configurable remote ip addresses. At the remote end, gamebridge accepts the incoming traffic and injects it back into the local network. gamebridge can be configured to mesh multiple ip addresses together in a peer-to-peer configuration, or a centralized copy of the program can be configured to act as a relay, serving a number of clients, (in a client-server, or "star", configuration).
xboxbridge is a shell script that uses gamebridge to connect two or more Xbox consoles.
You can download the tools, (version 1.0 beta), here: gamebridge-1.0b.tar.gz
Please note that this is a beta release. I have not done much testing except to verify that simple traffic is transported over my local network. Send feedback and fixes to: email@example.com.
To install, execute the following commands in the download folder:
tar xvf gamebridge-1.0b.tar
