IMPORTANT: CoA works by accepting inbound traffic from our RADIUS. We will send this request back to the same WAN IP of which your master IAP (virtual controller) uses for outbound traffic to our RADIUS. Therefore, you will need to forward port 3799 (UDP) on your firewall from this WAN IP to the virtual controller IP on your local network.
