I installed Fusionpbx with install script on one virtual machine. Set the config to save internal freeswitch database in postgresql.everything is ok intenal database tables was created. I copied virtual machine and changed its IP address. In second virtual machine I set core database to IP and password of first virtual machine and set same switchname in switch.conf.xml But in second virtual machine even freeswitch didnot start. What is problem? Is there any firwal rules closing database access from another IP except 127.0.0.1 ?
