Load balancing with same source port, but different target ports
I want to explore the option to use DigitalOcean's load balancer to balance between different node instances on the same droplet (listening on different ports) - in order to utilize all the cores in a droplet. I guess it's possible to do this with something like nginx, but I want to offload the processing to the load balancer.
Here's a screenshot illustrating the issue:
It's not possible to set the same source port (https - 443) but different target ports in DigitalOcean's load balancer configuration.
Anyone knows if this is a known limitation? Or maybe there are plans to support it in the future? Or maybe some other idea?
