Gateway setup

[Fuggin]

I currently have an ATT modem that I plan to put in IP passthrough. It's gateway is 192.168.1.254.

I put the OPNsense LAN port static IP as 192.168.1.1. Plan to enable DHCP range of 192.168.1.40-192.168.1.200.

I have bunch of static IP devices between .1-.39.

In the OPNsense gateway settings, would I enter 192.168.1.1 since it is the new router?
