Initial Setup Guide

Welcome to Firewalla RED.  Eager to get started?  Let's do it!

This guide has everything you need to know to set up the little red box.  If at any stage you are stuck or have questions, please email us at, it will create a support case.

STEP 1: Wire up the box

Connect Firewalla device to the main router of your network using the Ethernet cable provided in the package.  Then, connect the device to a power source using the Micro-USB cable provided in the package.


  • For best performance, the Firewalla device needs to be installed next to the main router (not the extender). That is the router either provided by your service provider or purchased by you. If you have multiple routers, Firewalla must be connected to the same network as your mobile phone is connected to. If you don’t understand this, it is likely your network is not complex enough, just plug in Firewalla to your main router.
  • You can connect the Firewalla to any power source.  Make sure it provides a decent 1A current.  Once the device is powered, the light next to the  Ethernet cable will start blinking.
  • Do not power off the box during the installation.

STEP 2: Download and install Firewalla App

You can search and download “Firewalla” App from App Store (for iOS) or Google Play (for Android). Or you can just click the icon below to go directly to the download page.


STEP 3: Connect Firewalla App to talk to the box

Launch Firewalla App, if the red box is ready to be paired, you shall see either '+' or 'New Firewalla' icon, or see both icons.  If you don't see any of the two icons, please be patient.  Because first time Firewalla comes up, it will download and upgrade to the latest software.  This may take up to 5 mins.

Starting pair with the red box, tap on either '+' or 'New Firewalla' icon, and follow the instruction on the wizard to guide you through the process.  When asked to scan QR code, it is the sticker located at the bottom of the little red box.  Once it is finished, your box will be able to communicate with the app. 



STEP 4: Initial Setup of the box

After connecting the device, a setup dialog will automatically appear on App. Tap “Continue”, it will automatically setup the device by learning your network. The entire process may take several more minutes. Once it is done, the little red box is now ready to work.


  • If during the setup process, the device finds your main router is not compatible with Simple Mode, it will advise you to use DHCP Mode instead.  However, DHCP mode requires some manual configuration on your router.  Please follow this guide to setup DHCP mode.
  • If you want to know what is Simple Mode and DHCP Mode before deciding which mode to choose, check out this page
  • If you just want to see whether your router is compatible with Simple Mode or not, check out this page.
  • If you are sure your router is compatible with Simple Mode, feel free to retry when you see the test fail message.
