Not Identifiying All Devices

I have found devices on my network which Firewalla is not detecting.  Is anyone else experiencing this?

  What type of devices are these?  We are aware some of the low energy or lower power devices that don't activate (not replying at the network level) are harder to detect in Simple Mode.  Give DHCP mode a try if you can, should be able to see better.

  I'm in DHCP mode and having this issue. It doesn't see two of my foscams. They are connected via extender.

  The Firewalla has an IP of 192.168.1.5 and the overlay IP of 192.168.1.254.

  Should i put the 192.168.1.254 addy as the gateway on the extender? Despite it still being 192.168.1.1 on the extenders, the foscams connect and pull a DHCP address. I checked and the gateway is set to 192.168.1.254 but Firewalla doesn't see it them in the device listing. 

  Am i missing a configuration step somewhere? My main router is Linksys EA9300. The backyard extender is a Linksys RE9000. 

  The front yard extender is Netgear EX3700. Firewalla can see the devices connected to the netgear extenders just not the linksys extender.

   

  I hope this makes sense :p

  If your extender running as an extender or a router?  (meaning, devices connected to the extender,  do they have their own IP range?)

  It's in extender mode. 

  Devices that connect to it pull a proper IP and gateway of the firewalla. However they don't show up as i would expect in the device listing. 

   

  all the extenders have static IP's if that matters. 

  My setup:

  Main Router             192.168.1.1 (DHCP OFF)

  Backyard extender  192.168.1.2 (gateway set to 192.168.1.1, DNS 192.168.1.1)

  Front Yard extender 192.168.1.3 (gateway set to 192.168.1.1, DNS 192.168.1.1)

  Shop Extender         192.168.1.4 (gateway set to 192.168.1.1, DNS 192.168.1.1)

  Firewalla                  192.168.1.5   (overlay IP is 192.168.1.254) (DHCP mode, Scope 192.168.1.100-250)

   

  Main Router - Linksys EA9300

  BackYard -    Linksys R9000 (5ghz backhaul, serves 2.4Ghz clients)

  FrontYard  - Netgear EX3700 (5ghz backhaul, serves only 2.4Ghz clients)

  Shop  -     Netgear EX3700 (5Ghz backhaul, serves only 2.4Ghz clients)

  With extenders, two things can happen

  1. Extenders that bridge MAC's.   Here, extenders will create a new MAC for your device behind it, and use it to bridge to your main router.  When this happens, you actually will have two MAC's for the same device (likely some digits of the MAC address will be the same). Here in firewalla, you will see two different devices.

  2. Extenders that are like routers.  Here you talk to the extender and extender NAT your devices.  Firewalla don't see anything besides the extender.  

  Both of these could happen, check your settings on the extenders if you can.
