Cannot subscribe the 2nd room mix stream

[zhouhuirun2015]

Join room a, subscribe room a's stream, public own local stream, mix a stream, all functions well.
Join room b, subscribe room b's mix stream, success, but no stream rendered.

The webrtc_agent report:

Hi, it seems that your internal port range is too small.
Change the port range under [internal] section in webrtc_agent/agent.toml and have a try.

[zhouhuirun2015]

This doesn't work,
The webrtc_agent port range is from 20000 ~ 30000 or 10000 ~ 60000

All tested, not worked.

Not every time the stream not rendered.

[starwarfan]

the "maxport" should be larger than "minport", for both [internal] and [webrtc] sections.

[zhouhuirun2015]

min port and max port in [internal] and [webrtc] sections:
10000 and 60000

[zhouhuirun2015]

I wrote a script file to test the server tcp port range open, it's ok.
Not the server's port problem.

I specified min: 1025 and max: 65535, still facing this problem.
