I do not have my firewall on in my synology on. It's a home network behind my router's firewall so I don't see the need. I was tired of the Unifi controller crashing so I finally ran it on docker on my NAS by following the steps in this post: here. Now I am getting the error on my devices:
This device is not able to connect to the internal STUN server on your Controller. Please check if the device is able to reach the STUN server on port 3478
I've tried to read up on this, your network can work with this error, which mine does. I do want the error gone. I have tried a port forwarding rule in the controller. My whole system is in one network, so not sure why all the requests to port forward (i guess logging in from the outside?).
