I install turnserver-4.5.0.6.
ifconfig 's message is:

          inet addr:175.102.16.35  Bcast:175.102.16.127  Mask:255.255.255.128

I check NAT type from 175.102.16.78, the NAT type is:PortRestrictedCone.
I check NAT type from 175.102.16.35, the NAT type is:RestrictedCone.
In the second way, coturn don't return 175.102.16.78 in the bind response。
I have check udp packet in wireshark.
This is why?

Thank you.
