Transparent Filtering Bridge problem

[spidysense]

I am trying to create a transparent filtering bridge.
My setup is: Internet-->Opnsense Filtering Bridge-->Router-->Lan
I followed these instructions: https://docs.opnsense.org/manual/how-tos/transparent_bridge.html?

Step 4. "Now Add an IP address to the interface that you would like to use to manage the bridge. Go to Interfaces -> OPT1 enable the interface and fill-in the ip/netmask." I think these instructions are outdated here. There is nowhere to enter the IP. I assume I can do this by going to Interfaces -> LAN & Interfaces -> OPT1, change the IPV4 configuration type to static and then set the IP address which I did to 192.168.1.3.

My Bridge OPT1 is 192.168.1.3
My Router is 192.168.1.1

I cannot access the Opnsense firewall any longer, but the bridge works.
Any ideas?

If you have L3 switch for your LAN and using VLAN routing then please configure a new route toward to switch also.
