I would really need to think about your question, but, for inside your LAN you can only use LE certs an FQDN's that are valid internally, so probably not proxy.intranet.mydomain.com. What you can do to get round that is in your internal DNS server, make your external FQDN's resolve to the ClearOS LAN IP and then use the external FQDN internally.
