  Realms are global, as are modules.

  No.  The "if  / else" unlang keywords *cannot* go into proxy.conf or into a module configuration.  They can *only* appear inside of a virtual server "authorize", etc. section.

  If you created a virtual server, why?  How do you think that requests from the client get sent to a virtual server?

  Read raddb/sites-available/README.  This documents how virtual servers work.

  If all packets are coming from one NAS, then virtual servers are not the answer.  If each realm comes from a different NAS, then you can use virtual servers.
