Question about creating rules for untrusted LAN hosts

[xtrasyn]

Hi all, I’m a bit of a noob on this so I’d really like some advice and/or help.

I have a opnsense install, which is connected to a switch, and on that switch I have cables to several routers on a mesh wifi network.

On those routers I have my ‘trusted’ bridged network (dhcp done by the opnsense box, 192.168.0.x/24) and a guest network (which is a feature of the mesh wifi routers). Every client on the ‘guest’ network gets ip’s in the 192.168.3.x/24 range. I can’t adjust that network, it’s factory standard.

I have a few devices that I don’t trust 100%, so I configured them to use the guest network. I’d like them to have the same firewall protection as the WAN side of the opnsense box.

Is such a thing feasible or is that a pipe dream? How would I go about with such a thing? What changes would I have to make and what things should I check?

Thanks in advance for any pointers or help.

Hi,

There's a nice explanation how to block access and how to configure firewall rules in OPNsense by Dustin Casto.
