Hi,

I have a bit if a weird setup at home and wanted to understand how Firewalla determines which gateway IP to spoof ARP for, before I go and purchase a Firewalla Blue.

Current setup is:

Internet -> Edgerouter Lite (x.x.x.1) -> Ruckus switch/router (x.x.x.254) -> All clients received .254 as Gateway.

I want Firewalla to only spoof for x.x.x.1 gateway, but DHCP is handing out x.x.x.254. Can I manually specify in the config as to which address I want it to spoof for?

  The gateway is from DHCP.  So if you are running a custom DHCP server, possible to give firewalla the x.x.x.1?  If not you have two options

  1. Under Advanced->Network Settings->Primary Network tap on edit
