LAGG + VLANs + Bridge to get same IP address for a device connected to any port

[opnsenseuser1]

Hi,
I recently purchased a router / device has 6 (I226-V 2.5Gbps) ports device.
I have been trying to set up VLANs in combination with LAGG and bridge, so that if I connect a particular device to any of the ports (except WAN igc0) the connected device should get consistently same IP address via DHCP static IP and MAC mappings, but I have not been able to get it to work.

Did any one do this kind of setup ? If so can you please share all the steps required to complete this setup ?

Is this setup possible at all ?

Thank you in advance.
