Shifted to LEDE from CC, TL-WR841N v9. During the process relayd and luci-proto-relay would not install with the GUI - bad gateway message. Installed fine from the CLI. Started and enabled relayd, worked fine however, although enabled, it would not start on reboot. Added sleep 10 and /etc/init.d/relayd to /etc/rc.local. "Fixed."
Cool!, just in case you need a Routed Client with RelayD and IGMPProxy with: https://gist.github.com/braian87b/821e9e4f399918510c55619192a31871 or Wireless Links using WDS on atheros: https://gist.github.com/braian87b/8a524a8ad74a36407a8f481e9d16a5c9
