We have a local environment for testing our cloud WebRTC products. The media application runs locally on a MacBook along with a node.js server application. We connect using a web page which establishes connections. Our media application can be configured to use the localhost interface by default but also supports any non-localhost interface. On my MacBook (M1, macOS 14.3.1) I can no longer use the non-localhost interface. Wireshark captures show that STUN messages from the web application fail to get responded to on the non-localhost interface. Others who use a similar setup and the same software versions do not experience this issue. This used to work for me as well.
What are my options for debugging this issue?
Thanks, Bob
