Archer C7 leaking traffic

Installing and Using OpenWrt

I recently discovered that some routers configure the switch to pass all traffic, prior to the OS booting and having the real config applied. Subsequently, you can get traffic leaking between ports that are supposed to be isolated.

Does anyone know whether Archer C7 routers have this issue? I plan to test it manually, but I would prefer to not rely upon a test that I may or may not do correctly.

How much real traffic do you have before the dnsmasq has started and handed out ip leases to all clients?

That usually takes “very long” time after the router boot has finished.
