    Missing Devices:

    Most time we see this issue is related to how your network is segmented.  Please check if these units that are missing are on the same network (have the same IP address subnet) as firewalla.  This may sound stupid, but we do see some of our customers have a few wifi access points with different networks.

    Next, there are some low power devices that don't wake up until it triggered.  Which means, this may take some time for the system to see them.  (example, battery-powered IP devices, such as the Apple Watch)

     

    Devices not stopping internet:

    https://help.firewalla.com/hc/en-us/articles/360000555074-Troubleshooting-When-Running-Firewalla-

    Please see this article, there are a few things that may happen.  And some may be related to ipv6 and the ipv6 feature is not enabled by default.  (tap on + then ipv6 button)

    An update to this.

    I've disconnected the fingbox - youtube is still available via app and browser across any device, despite the Video Block being in place.

    I then tried creating a bunch of rules blocking:

    m.youtube.com
    ytimg.com
    ytimg.l.google.com
    youtube.l.google.com
    youtube.com
    googlevideo.com

    This seems to work, but unfortunately it also means i can't get to google.com in a browser. To enable google again I have to have m.youtube.com and youtube.com rules disabled, which obviously means youtube now works again!

    I used to be able to do this with my pihole with no issues. I'm thinking i may have to revert to that and get rid of the firewalla. :(

    One possible avenue to look at is that my main router has DNS servers set to cleanbrowsing.org servers. If I point that DNS at the firewalla would that make a difference?

    Thanks

    Mark

    Ok. A further update.

    I've pointed the router DNS settings to use the Filewalla as both primary and secondary DNS. Even with this no blocking takes place on any of the mobile devices (via browser or youtube app). It does however block youtube via the browser on my macbook.

    I'm at a loss now. I just can't see why the mobile devices just keep working. Damn you google!

    Thanks

    Mark

    I am having exactly the same issue with my new Firewalla Blue.   YouTube is not blocked on mobile devices and some devices are seen but their activity is not reflected.    Turning on the ipv6 feature seems to have worked to detect activity on an iPhone but YouTube still gets through and my desktop still shows no activity despite me watching streaming video.   This is frustrating - as one of the main reasons that I bought Firewalla was the ability to shut down YouTube on command.

    Further update.    The inability to monitor activity on certain devices and the YouTube thing appear to be related.   The additional data points that lead me in this direction are:

    >   With the video block turned on for a desktop I was able to access YouTube.  However, when I went to another video site (full30) the blocker worked. 

    >  When I lifted the video block and went back to full30 firewall registered the activity.

    Google is evil

    Thanks George, i'm glad i'm not imagining it!

    For me the Video block does kill Google services such as logging into Google calendar on the macbook, and only intermittently blocks youtube.

    I do see activity graphs for all devices, it just doesn't block youtube.

    I'm interested that on the pihole does block exactly what I want with:

    (^|\.)googlevideo\.com$

    (^|\.)youtube\.com$
     
    But the blanket equivalents on the firewalla just kill all google stuff, except youtube!
     
    I'm guessing this is a different OSI layer thing - the pihole does this at the 'name' level, and the firewalla does it at an IP level.
     
    I'm also guessing that youtube has so many IPs that it's almost impossible to block...

    Hi Mark.    While I am still unable to block YouTube, turning on safe search and family protect appears to block a great deal of YouTube content.  I will get by with that until we get an answer from firewalla.

    Thanks George - yes I had noticed that too, that's a good start! If only Google classified it's content better...
