Source Side Deduplication / using own ports for data transfer?

Hey guys,

when i enable the source side deduplication which ports must be open for data transfer?

In omnirc file i found few variables which can be associated with the deduplicated data transfer:

#===========================================================================
#   Variables which can be used for StoreOnceSoftware
#===========================================================================
#
#  OB2_STOREONCESOFTWARE_COMMAND_PORT=1-65535
#    Default: 9387 
#    The port on which StoreOnceSoftware daemon/service waits to receive 
#    connections from MA. MA will have to use the same port in order to connect to
#    StoreOnceSoftware daemon/service.
#
#  OB2_STOREONCESOFTWARE_DATA_PORT=1-65535
#    Default: 9388
#    The port on which StoreOnceSoftware daemon/service waits to receive 
#    data from MA.

#===========================================================================
#   Variables which can be used for StoreOnce Backup System 
#===========================================================================
#
#  OB2D2D_COMMAND_PORT=1-65535
#   This variable changes the port which is used for command communication between the Media Agent and the StoreOnce Backup system.
#   For example: OB2D2D_COMMAND_PORT =12345
#   Default: 9387
#
#  OB2D2D_DATA_PORT=1-65535
#   This variable changes the port which is used for data communication between the Media Agent and the StoreOnce Backup system utility.
#   For example: OB2D2D_DATA_PORT=12346
#   Default: 9388

Whats the difference between this four points?

Actual, we have a very strictness firewall between the client and the cellserver. And i get no connection to our StoreOnce device..

Got error: "StoreOnce error: StoreOnce device offline, network error occurred or secure communication failed while contacting the StoreOnce device"

Maybe someone  can help :)

greetings,
