How to redirect incoming traffic to all virtual machines?

Question

Network routing

I ran into a problem, on the diagram I displayed an approximate planned network of virtual machines.
Now all traffic is redirected to only one of the N number of containers (ports 80 and 443)
But I want to use other VMs, how and where to direct incoming traffic so that all VMs ( within the framework of the services installed on them) participated in the exchange of information?
If the question is not quite correctly asked, then I’ll go from the other side:
Conventionally, there are 2 containers, each with 5 sites, now only the 1st one works, the second traffic does not receive how to direct traffic in such a way that both the second and Nth containers are on equal terms with the first?
