Hello.
I have a configuration with a single server and many remote computers not reachable through VPN.
There are many agents behind a single firewall.

How can I manage multiple remote computers behind a single firewall from my server ?
How can I tell my server to reach these multiple agents or is it a possibility to tell each agent what is the IP address of the server ?

Regards.

As Reflect's Central Management Console development remains in beta according to the latest KB article I've seen, it would probably be best to communicate directly with the Macrium team on the subject.  I don't have the CMC beta installed myself, but as best I understand it, it relies on Microsoft Message Queuing for its agent-server interactions for both Domain and Workgroup networks.
