Hello, I am seeking insight regarding the Rancher agent that is run on the remote cluster. We would like to run a cluster on an isolated network (Azure) and communicate to Rancher server over a private endpoint on one IP address. Is this not possible with the Rancher import agent? I had hoped only port 6443, and all ports for that matter, on a single IP would be enough for the agent to talk to the server, but it is not importing. Does Rancher server require unfettered access to the network of the remote cluster, such as peering with that network? I would have hoped we would be able to leverage the agent for isolated networks, but it appears to have more access requirements than I had thought. Thank you!
