Nimbostratus
NimbostratusF5 has a feature to allow its pool members to be based off of a FQDN rather than an IP address. If you add your pool members as a FQDN node, this means you can have your public domain name resolve to the F5 virtual server address and then have that virtual server send requests to any server attached to your local domain name. The responses will look to the user as if they are coming from the public domain name. Hopefully this solution works for you. FaceTime Android
Fqdn isn't the answer here since the node addresses are known.
