I'm running on Ubuntu 18.04 with Docker version 18.03.0-ce, build 0520e24. I have ports 500 and 4500 open in my firewall for UDP, and the below log shows a connection attempt from my client IP address (Windows 10, with the registry "hack" applied). Clearly udp_xmit failed to 71.105.XXX.XX:1701 with err=-1:No such device,
looks suspicious. I am running from a pull today from the github repository. Any help would be appreciated.
