if peer reflexive works, it makes sense to avoid using a relay after all.
Stuff can still fail after that though.
Hi,

I found a strange problem on my side. I have a PC under Airport WiFi AP
(but connected by wire), and try to use RTCPeerConnection to connect the
other device. However, the ice status is changed as "connected", but I
can't see any video on my FF. I also try to use about:webrtc to find the
any clue.. Here is the output from about:webrtc

Airport and hotel wifi/routers/firewalls are often horribly draconian, and in particular often will not allow peer-to-peer (peer reflexive) operation for various reasons (starting with protecting users from other users with viruses who are behind the same firewall, and less 'nice' reasons as well). Now, this may not be your issue since it seems to have selected peer-reflexive and presumably that requires packets to pass between them. However: The network situation may also be odd since I see both 192.168.x.x and 10.x.x.x addresses in use. Multiple interfaces? layered NATs?

Finally, FF decides to use 192.168.3.10:45673, and Turn Server is
canceled. But I still can not see any video on my FF? Why?

Does anyone know how to fix this issue?

Thanks.
