Will this work as a simple routing and NAT solution so each customer has public IP address?
From upstream router, route all the IP address as /32 to the condo’s routers current public address. On Condo router add below.
/ip address add address=x.x.80.69/32 interface=wan
/ip firewall nat add chain=dstnat dst-address=x.x.80.69 action=dst-nat to-addresses=192.168.110.1
/ip firewall nat add chain=srcnat src-address=192.168.110.1/24 action=src-nat to-addresses= x.x.80.69
Do this for each customer network.
Each condo unit has its own vlan and subnet.
This is not a hotspot service!
