Firewalla Gold is optimized to use in Router Mode.
If you already have a router/multiple routers, to avoid double NAT in your network, we highly recommend that you turn off the routing function on your Wi-Fi router (change it to Bridge mode or AP Mode), and use your router as an additional Wi-Fi access point connected to Firewalla Gold's LAN port.
Here are some examples of how this is configured on popular routers. If your router is not on this list, please refer to your router's manual.
1) Login to your Netgear router. 2) Navigate to "Advanced" -> "Advanced Setup" -> "Router/AP/Bridge Mode". 3) Choose "AP Mode". 4) Apply.

NOTE: If you are wiring your eero units. The first eero (gateway eero) must be directly after Firewalla if eero is not used as a router. All other units, part of the same mesh, will need to come off of one switch from the second ethernet of first gateway eero.
So it has to be Firewall -> gateway eero -> switch => other eero units
Otherwise, it'll cause network loop and bring down the performance dramatically.

Tips for Pros
@Spblhedeam send us this link. Seems on some routers using the LAN port (instead of WAN port) may increase performance. https://community.netgear.com/t5/Nighthawk-WiFi-Routers/WAN-OR-LAN-Port-for-Access-Point/m-p/1066752#M29745
