Hello Jens
Ok you need to clarify what do you mean by "Loadrunner and MI Listener are on the same machine. " and then "A controller and a Proxy Machine are on the other side from the firewall." maybe you are just conused with the names and you are doing everything ok, but still let me clarify. Controller and MiListener MUST be on the same firewall side, only LoadGenerator can be on the other side, it must be configured to work with firewall and the only port you need open is the 443, that should point to the MiListener machine.
hope this helps
