Monitoring over Firewall : establish connection to monitor automatically

Hi

I use Loadrunner 11.52 over a Firewall. 2 Machines with Loadcontroller for Vuser scripts and one machine is configured for monitoring over firewall. LR Agent works as service on this machines. All of this three machines connect the MI listener over the firewall. Mi Listener and Loaccontroller are on the same machine. 

All works fine, when the connection to the Monitoring machine is established.  The Monitoring get the data from the servers configures servers,as it should be.

I testthe availability of theloadgeneratorsin the consolethey are displayed as"ready". I do not dothis,the status of themonitormachineremains "down"and therearenomonitortransferringdata.

Is it possibleto connect to themonitorwas automaticallyactivatewhenyou testfor example at night?
