[yasir malik]

Hi,

I have setup coturn on ubuntu vps server. Here is my turnserver.

. 

When i test it through Trickle ICE using following turnserver url turn:ipaddress:3478?transport=udp. It returns that it is not reachable. Here is the return result.

Time	Component	Type	Foundation	Protocol	Address	Port	Priority
40.167	Not reachable?

I am getting the response of rely when i use tcp. 

Time	Component	Type	Foundation	Protocol	Address	Port	Priority
