i just set up an open sense box and need to block 2 ports from talking. on my unifi router i had port 1 set to be for phones tvs and computers and port 2 was all my iot things like google home/lights/switches ect. i had it set so my iot things on port 2 couldnt see or talk to my non iot items on port 1 and vice versa
how do i set up firewall rules on opn sense to do that
thanks
Assign the interface for each port to a different subnet and keep the networks connected to them separated.
If they share network hardware - switches or access points - you need to set up VLAN's and different SSID's.

Adding to that by way clarification, OPNsense blocks traffic between subnets by default. To allow traffic requires specific rules. These can allow one-way or two-way traffic initiation, so you could allow your computers to contact IoT devices but not vice versa, for example.
