Hi,

Old setup, Fiber converter -> DIR-636L Wired&WiFi -> DecoS4x3 Wired&WiFi

DIR-636L manages an IoT network with cameras, heating, refrigerator, light switches. Cisco ATA...

This network is always on.

Deco is used for phones and computers when I am in the house, and all the Decos are switched off

when I leave. Different SSIDs and LANs on the two networks.

New setup, wanted but not managed to get yet;

Deco S4x3 Wired&Wifi -> Deco M5x3 Wired&Wifi.

Deco S4 replacing the DIR-636L and the new 3 Deco M5s replacing the S4s.

I cannot get a dhcp addres on the M5 when wired to the S4.

I would prefer to have a firewall between the two networks if possible.

Is this setup doable with all Decos?

Cheers,

Mike
