I test rawrtc-terminal-demo. js on Windows7, and rawrtc-terminal run in Ubuntu(in virtualbox) on the same PC. Test case fail in firefox, but pass in Chrome.

Thank you.

hi all: I think this is because the implement of Firefox. My PC in a WIFI condition, My PC local ip is: 192.168.1.103, and router ip is:10.8.114.103 ，public ip:36.251.248.186 Another peer local ip is: 10.8.117.44, public ip:36.251.248.186

When we all use Chrome, we can build p2p connection. Then p2p hole process is:

When we all use Firefox, we can't build p2p connection. The p2p hole process is:

FireFox send stun Binding Request by ip which get from a signal server. And Chrome directly send stun Binding Response when it receive Binding Request.

This is right? @lgrahl

Without logs from Firefox, the cause of the failure is hard to tell.

How to get logs ? @lgrahl
