Modem change and loss of MX connectivity

We are a super small rural school district and I am super green. We changed modems from Comcast to Century Link. It cut off our Meraki firewall. This is a screenshot from my test office network. If I leave NAT and DHCP on, on the modem then the Meraki works. If I turn off NAT and DHCP at the modem, since the MX does that, the internet dies. I tried putting the modem in transparency mode with a variety of VLANs. I was hoping to get away with the default vlan. I would be super grateful for any advice or help you have to offer.
