I have a cluster of servers (AWS EC2) that need to contact a specific host.
This host is currently whitelisting all the server's IPs.
The problem is that we are adding more servers to the cluster, and have to contact many customers to whitelist the new servers.
So I am wondering if there is a way to route all the outbound requests through a specific IP (or pre-defined set of IPs), so customers dont need to worry about white-listening new servers as it comes.
