No.

If you can describe what problem you are trying to solve with that, maybe there is another solution that Deco mesh can provide.

  @Alexandre. 

DECO are as router mode, connected to my LAN protected with pfSense/Snort.

I want to let guest Wi-Fi with less restrictions.

Thanks.

Are you sure that your LAN can see IP addresses of devices connected to Deco mesh? My assumption would be that your LAN (and pfSense/Snort) will only see Main Deco IP address. Am I mistaken?

Perhaps, a network diagram could help.

  @Alexandre. 

Lan devices don't connect to Deco clients, but deco clients trafic goes thru snort to access Internet.

I want main Wi-Fi to connect to LAN, but don't want Guest Wi-Fi to do that.

If it's possible to setup guest on 172.16.4.0/24 network, that guest clients will route to another link.

2º link ======== router (172.16.4.1)

This is all you could have with Deco mesh:

You can't use both Main Deco Ethernet ports as WAN ports each with different subnet behind, if this is what you are asking. 

Your pfsense will see all traffic coming from Main Deco on IP address 192.168.0.60.

I am curious if you ever had that setup that you want from Deco mesh and if you did - how you managed to have it. I doubt that any standard household WiFi router you can put behind pfsense will allow you to do what you want to do with Deco mesh.
