UDP Bridge is a free Chrome add-on designed to facilitate the bridging of UDP packets between external/internal networks and ChromeOS Linux virtual machines or containers. This tool enables users to forward UDP packets from a Chromebook or ChromeOS to specified IP addresses, making it particularly useful for those running UDP-based server logic within a virtual environment. The application runs locally on ChromeOS, ensuring functionality even when offline, and allows for the monitoring of specified ports to forward incoming packets efficiently.

In addition to basic packet forwarding, UDP Bridge includes functionality for joining and leaving multicast groups, enhancing its capability to handle multicast packets. Users can configure the local IP binding for the socket, although it defaults toHowever, it is important to note that due to the nature of UDP sockets used, the source IP and port of forwarded packets may be altered to reflect ChromeOS's own IP. Overall, UDP Bridge provides a practical solution for networking within ChromeOS environments.
