Newbie to OPNsense question - ASUS router behind as wireless router or AP

[Dzoker]

Hi All,

New here and newbie with OPNsense. What I'm trying to do is have OPNS handle my routing and FW and 2 x ASUS routers handling my wireless devices (I already have the 2 x ASUS routers).
One ASUS is currently connected to OPNS to one of the two NIC card ports (LAN_2 interface 192.168.2.1). The idea is to have this network to be for my IOT devices (unsecured).

I have another ASUS that I want to connect in similar matter to the 2nd port of my NIC card (LAN_1 interface 192.168.1.1) and use that for my trusted devices (secured). I already have FW rules that allow traffic from LAN_1 to all and restrict LAN_2 towards LAN_1 and allow internet.

The question is should I set up the ASUS routers as AP or wireless router? For testing purpose I already have ASUS 2 router (LAN_2) connected as AP bu I'm not sure if that is ok or not. I tried using it as a wireless router but was unable to connect it in the process.

Hope this makes sense.

Thank you

Leave the ASUS AP's as bridges (not routers) Make sure they don't introduce a second DHCP server either.

Thank you for your answer... I only have "Media Bridge" in my ASUS under operation mode... Is that what you are referring to?

I currently have it set up as "Access Point(AP) mode / AiMesh Router in AP mode"

Choices in ASUS:
- Wireless router mode / AiMesh Router mode (Default)
- Access Point(AP) mode / AiMesh Router in AP mode
- Repeater mode
- Media Bridge
- AiMesh Node

Access Point mode (as described at https://www.asus.com/support/faq/1015009/) sounds like what you want.
