Using Apple's Network Framework, is there a way to do connectionless UDP?

Question

I'm trying to establish a peer to peer datagram exchange. Ya, I'm doing hole punching and using a remote stun server. Unfortunately, I'm finding that I have to use GCDAsycnUdpSocket, which, while a fine library, isn't quite as convenient as Network. However, it seems you have to create a bound connection with Network framework in order to send, which later results in ICMP rejection. For now, it seems I need to use GCDAsycnUdpSocket, where I can do connectionless sending. However, I thought I'd reach out to see if I overlooked something in the Network framework which would let me send/receive without creating a bound connection. As an aside, I did try setting the includePeerToPeer to true in the connection creation, but that didn't seem to help.
