VCD Console Proxy port load balancing in VCD 10.0 virtual appliance architecture

We're deploying VCD 10.0 based on the virtual appliance architecture with 3 cells. As you might know in this architecture the console proxy and UI use the same IP address with different ports. We need clarification about how to load balance the cells for Internet access. Our understanding is the UI port (TCP 443) is the one that needs to be balanced and the console proxy port (TCP 8443) needs direct access wihtout balancing, the one that we're confused is how to provide access from internet for console access since all cells are using the same TCP port and they will be accessed from the same public IP,

thanks in advance
