Sorry, I don't understand the meaning of ssh-forwarded real-IPs. Ssh
is usually doing the encryption on the application-layer. Or, are you
mentioning the CIPE?

Yeah, you can use VPN (or CIPE) to map some external real servers into
your private cluster network. If you use LVS-NAT, make sure the
routing on the real server must be configuration properly so that the
response packets will go through the load balancer to the clients.
