How to troubleshoot when not able to see network traffic on Firewalla App

2. Resolution

If the graphs come out empty, please check the following:

1. Make sure the box monitoring mode is on. If there is a light gray dot on the monitor button, tap on the monitor button, and either turn on Simple or DHCP mode.
2. If you are in DHCP mode, likely some devices don't have the new IP.  Disconnect and reconnect the device to the network and you should be fine. Double-check that your router's DHCP server is off. 
3. Check the device menu and make sure the device internet or monitoring option is not off.
4. Check if the device is an ipv6 only device.  If it is, Tap on "+" and enable the ipv6 service. 

5. Check if you have any network extenders such as EX3700.  These extenders will hide MAC or randomize the real MAC addresses, which make tracking impossible.  

If the graphs are showing something

• Very likely the problem is some flows or network traffic is going over IPv6.  To check, try to block that particular device and try to visit https://firewalla.com and https://google.com,if  firewalla.com fails and google.com succeeds, then follow above to enable IPv6.
