________________________________
I reviewed the diff as well and have the following comments:
- In the initial discussion of allowing STUN packets, it mentions that STUN checks can occur while the client is preparing permission requests. I think this could be worded more clearly, e.g.
".... addressing the race condition that exists when the remote peer sends connectivity checks before the local client has had a chance to create permissions in the TURN server for the remote peer IP addresses."

- Nit: In Section 19, 'atrributes' typo

I reviewed the diff between version 17 and 18 and the changes to allow a TURN server to forward inbound STUN messages if configured so look good to me.

>> Abstract:
>>   If a host is located behind a NAT, then in certain situations it can
>>   be impossible for that host to communicate directly with other hosts
>>   (peers).  In these situations, it is necessary for the host to use
>>   the services of an intermediate node that acts as a communication
>>   relay.  This specification defines a protocol, called TURN (Traversal
>>   Using Relays around NAT), that allows the host to control the
>>   operation of the relay and to exchange packets with its peers using
>>   the relay.  TURN differs from some other relay control protocols in
>>   that it allows a client to communicate with multiple peers using a
>>   single relay address.
>>
>>   The TURN protocol was designed to be used as part of the ICE
>>   (Interactive Connectivity Establishment) approach to NAT traversal,
>>   though it also can be used without ICE.
>>
>>   This document obsoletes RFC 5766 and RFC 6156.
