    Hi Shaun, 

    How are you screen sharing? VNC? SideCar? AirPlay ? What are you linking? (e.g. iPad + macOS). Are those devices on separate networks?

    On the mac I use Finder -> Network -> <laptop> and press the screen share button.

    MacBook Pro to MacBook Pro

    Same physical network but two different VLANS with a rule allowing access between the two devices.

    Hi Shaun, 

    So I think that needs Bonjour so at minimum, have you turned on mDNS on both networks?

    Yeah, mDNS is enabled for all networks.  I have no problems using airplay to screenshare a phone or device from one network to another.  The only problem seems to be osx to osx screen sharing.

    Just a quick update here... 

    This morning the whole network seemingly ground to a halt.  I couldn't get the my.firewalla.com web UI to load so I rebooted the Firewalla and all speeds are back to normal, including the mac to mac screen sharing.  

    I will add this though, I've been running this unit for about 1 week.  I also have one docker container and image on the Firewall to run the UniFi controller.  The docker image itself, as mentioned in the tutorial, is about 800MB; however, i'm using about 90% of the 3.4GB allocated to the docker space.  It appears that log files might be eating up a good portion of of available space.  

    I've been using docker for a number of years but I don't use it daily so I'm a bit rusty with it but not a total noob. Prune isn't going to help me here as I only have one container and image.  What else am I missing to help clean up the space?

    Well shoot... the network ground to a halt again forcing another reboot of Firewalla.  Not sure what is happening here.

    Can you trim or move docker to another partition? it may be the disk is full...  When the unit reboot, it will clean up some logs, but eventually it will get filled again

    The disk isn't full.  Still about 13% of the 3.4GB available; however, now i'm not sure this is docker related.  

    I have had the DNS freeze up multiple times this morning to the point where I can't even get to devices on my local network.  I've rebooted a couple of times.  

    Yesterday, I tried the beta software for the box and immediately had problems so I reverted back to stable.  Thats the only other variable I can think of that I have introduced in the last day to the new network setup.  

    I turned off DoH on the last reboot and things seem better for now.  Will monitor today.

    Today has been really bad.  At about 2:15 on a customer call DNS just stopped working. The call dropped.  Trying to ping gateway resulted in "host down".  I struggled for 45 minutes and two firewalla reboots to get it to come back up.  pings to internal devices were mostly unsuccessful.  Every once in a while something would get through but was 300 to 500 ms.

    I assume you checked all the AP/Cable and make sure they are good. And not using any customized DNS; 

    I have created a ticket, so someone can help you out

    Yes, APs were functioning. No custom DNS.
