Hi @Jotasan unfortunately the integrated SFP ports (ports 11 and 12 on the MX84) are LAN-only ports and cannot be leveraged as WAN1/2 interfaces. I looked for an override but do not see any option. We do have that ability on MX400/MX600 platforms where you could put in a 2x10G SFP+ module and run beta firmware to use those as WAN interfaces. Unfortunately on the MX84, you'll only have the copper RJ45 WAN interfaces and would have to use a media converter if the ISP handoff is fiber/LC only. Make a wish and I'll do the same with the team. Meraki is aware of these evolving requirements which is one reason why the newer 250/450 have dual SFP+ WAN interfaces.
