We used remote.domainFQDN to access our server which had a static IP. An A record at out domain name host provide was created with remote.domainFQDN having the static IP. The common name in the SSL was remote.domainFQDN. Worked beautifully
We now have a dynamic IP from the ISP. We signed up with dynDNS Pro and created a hostname servername.dyndns.org. DynDNS updater is installed on hte server and is updating regularly, as it should..
I do not know how to configure the A record at the domain hosting provider for a dynamic IP and what common name to use for the SSL, remote.domainFQDN or servername.dyndns.org
