To use Firewalla in DHCP Mode, it'll require you to disable DHCP service on Routers.
A small article on Simple mode vs. DHCP mode
For routers that don't provide an option to turn off the built-in DHCP service, here is a simple workaround.
Step 1: Connect Firewalla
Connect Firewalla to the Router. Connect Power. And wait for 5 to 7 min.
Step 2: Setup Firewalla to DHCP Mode
Launch the App, before starting to set up, pick "Manual Setup" => "DHCP Mode"
Step 3: Configure Your Router
Take Xfinity XB6 as an example here.
Login Router and Tap on Connected Devices
Step 3-1: Reserve an IP for Firewalla
Write down the IP of Firewalla, e.g. 10.0.0.237 (yours will be different)
Step 3-2: Limit DHCP
Tap on Connection->Local IP Network and limit the IP range to Firewalla IP Address (you got from step 4)
Original IP range:
Change both Beginning Address and Ending Address to Firewalla's IP Address:
If your router does not allow you to create a DHCP pool of 1 IP, you can try to reserve the additional IP's with fake devices.
Step 4: Done
Now you may need to reboot or wait for devices to start getting the 192.168.218.x address.
Notes on IPv6:
Some providers don't allow the router to fully disable or limit IPv6. When this happens, firewalla will not be able to manage any site that's IPv6. Resulting you can't see traffic or block any IPv6 sites. We are working on a solution, this may take a while. Example, if you block Firewalla.com it will work, but block google.com will not.

Today I have my Xfinity Gateway replaced because it was faulty, and for some reason this "tricky" no long works by
change both Beginning Address and Ending Address to Firewalla's IP Address... It says that the Beginning and Ending Address cannot be the same !
I think they send me with new firmware, because the gateway looks like the same as the old one!
What is the model of the xfinity gateway?
Hi there, follow the information about the gateway:
Gateway: Xfinity XB3
The DPC3941T should fully compatible with Simple mode. Are you having problems with it?
I'm running it with simple mode with no problem !
But if you desire to run it in DHCP mode, probably due a gateway firmware update it doesn't allow you to do this trick by set the IP range the same start and end.
My old gateway (same model) I was able to do this!
Thanks!
Correct. This no longer works on the XB6 as well.
@peter, any details on why it is not working on the XB6?
Same reason as posted above. No longer able to set the IP range to the same start and end. Work around may be putting device in bridge mode and using a supported router.
Peter, interesting. So the new firmware forcing at least 2 devices in DHCP? if that's the case, the method may also work (one device may not be able to be monitored).
Also, if you can, please try the "experimental simple mode" (you will need to turn on DHCP on your router first). Experimental simple mode is a set of customized fixes, that may make the router work.
