Branch office down if UTM down?

JamesGolden
Can someone please verify for me what I'm reading? As far as I can tell, regardless of what mode the RED devices are in, if the central office UTM is offline for any reason, the branch offices will have no Internet (assuming of course that the RED is the gateway device for the branch office). 
Is this correct?

    Hi, interesting to hear this. I've deployed many reds some years ago, and everytime the utm stops working (or no internet) the reds have started a reboot loop until the utm is back online, regardless which configuration i have used for. So i think this has changed over time?!

    Hmmm... good question; we've mostly deployed them in unified mode, so of course when the link to the UTM fails (ISP problems on either side/in between, power issues, etc.) after the RED tunnel is down long enough, it does reboot (assuming it's being reassigned/redeployed)... so yeah, I think even in split network mode, you will lose connectivity through the RED appliance as it will be rebooting, etc.

    If you need a site to run independently of a main UTM, etc. --- I suggest implementing a small UTM at that site instead of a RED.
