UDP Relay is maintained on the main branch; fixes are applied there and flow into the next tagged release. Please test against the latest main before reporting.

Please do not open a public GitHub issue for security vulnerabilities.

Instead, report them privately to kontakt@allegroit.dk (or use GitHub's private vulnerability reporting on this repository).

Please include:

• A description of the issue and its impact.
• Steps to reproduce (or a proof of concept).
• The affected host (Console or Windows Service) and OS / .NET version.

We aim to acknowledge reports within a few business days and will keep you updated as we work on a fix. Thank you for helping keep the project and its users safe.

UDP Relay forwards arbitrary UDP datagrams between endpoints you configure. When deploying on an untrusted network, bind the listeners to specific interfaces (set the *IP values in the Settings_*.xml to a specific address rather than 0.0.0.0) and restrict who can reach the relay's ports with your firewall.
