Hi All,

We have configured Licode MCU in private network and Natted with public IP  
and opened below ports in firewall

8080,443.3000,3001  
30000-31000 - UDP

Attached is the licode\_config file with the necessary changes

we are able to connect to the mcu but after some time audio and video  
getting blocked and video get stucks.  
checked the console log also but there is nothing regarding stream failed

immediatily when we try again it says ice connection failed and stream  
failed

it works sometimes only, but video will get stucks after sometime

Please let me know what all ports need to be opened

Thanks  
Naresh

Hi Naresh,

Looking to your config file I can see that you haven’t defined the ports  
(config.erizo.minport and config.erizo.maxport), that can be the reason of  
the fails. Otherwise I’d need more information to identify any other  
possible problems.

Best,
