HP B6960-90078 NOTE, Chapter, Using Both, Firewall Support, Variables Together, Port Usage in Data Protector

	Customizing the Data Protector Environment
	Firewall Support
NOTE	The OB2PORTRANGESPEC variable only applies to dynamically allocated
	ports. It does not affect the usage of the default Data Protector port
	number 5555.
	Defining a port range for a specific Data Protector agent process limits
	the port usage of this agent. It does not prevent other processes
	(applications or other Data Protector agents) from allocating ports from
	this range as well.
Using Both	If both variables OB2PORTRANGESPEC and OB2PORTRANGE are set,
Variables Together	OB2PORTRANGESPEC overrides the settings of OB2PORTRANGE.
	For example, the setting
	OB2PORTRANGESPEC=BMA-NET:18000-18009
	OB2PORTRANGE=22000-22499
	limits the port range used by the Media Agent to port numbers
	18000-18009, while all other Data Protector processes use port numbers
	from the range 22000-22499.
	By using both variables it is possible to force a specific agent to use only
	a dedicated port range (OB2PORTRANGESPEC) and, at the same time,
	prevent other Data Protector processes from selecting port numbers from
	this range.
	Port Usage in Data Protector
	The following section provides two tables that describe the port
	requirements of the different Data Protector components. Table 11-2
	breaks down the different Data Protector components and shows to
	which other components they can connect. It also defines the destination
	specification for the firewall rules. Table 11-3gives the same list of
	components but shows from which other components they can accept
	connections. It also determines the source port of the firewall rule.
