I need to use one of the droplets as a public ip that all backend scripts (on other droplets) connect through so the client can open one ip on their firewall but I can farm out the work to various servers.
droplet1/public IP droplet 2 connects private->droplet1->outbound to internet.
Is this possible and or easy to do in any way? Basically share a single outbound IP

Without know more about your actual use case, it’s hard to get more specific. Here are some tutorials that should point you in the right direction. These show you how to set up private networking and isolate a server:

After that, it really depends on how you need the servers to communicate. If you simply want to pass HTTP requests onto the droplet on the private network, you might want to look into using Nginx as a simple “load balancer.”
I don t understand very well the question, bit i think you need pat+nat. With nat you can share outbound your public ip (all machine behind tour router have the same IP outgoing.) pat you can translate port incoming
If you want to direct all traffic through the one machine, set it allow ip.forwarding and then set routes on them to use the one server as the gateway for certain destinations. You will have to adjust firewalls to match.
