User Defined Apps Template

Use this template to create user-defined applications (UDA).

Where can you use them?

n	Route Policy

n	QoS Policy

n	Optimization Policy

n	NAT Policy

n	Access Lists (ACL)

n	Application Groups

Behavior

n	For reporting symmetry, you must define the same application(s) on peer appliances. Otherwise, the application may be a UDA on one appliance, and yet be categorized as an unassigned application on another, paired appliance.

n	Each application consists of at least one rule.

n	A warning displays if you reach the maximum number of rules, ports, or addresses allowed.

n	If a UDA is in use, deleting it deletes all the dependent entries. A warning message appears before deletion.

n	Multiple UDAs can have the same name. Whenever that name is referenced, the software sequentially matches against each UDA definition having that name. So, dependent entries are only deleted when you delete the last definition of that UDA.

Note When it comes to flow and application statistics reports, user-defined applications are always checked before built-in applications.

Ports are unique. If a port or a range includes a built-in port, then the custom application is the one that lays claim to it.

If two distinctly named user-defined applications have a port number in common, then report results will be skewed, depending on the priority assigned to the custom applications. A port is only counted once.

Priority

n	Range = 1000 – 50000

n	Templates won't overwrite or delete applications on the appliances that have priorities in the range, 1 – 999.

n	By default, adding a rule/application increments the last Priority by 10.

Source or Destination

n	An IP address can specify a subnet - for example: 10.10.10.0/24.

n	An IP address can specify a range - for example: 10.10.10.20-30.

n	To allow any IP address, use 0.0.0.0/0.

n	Ports are available only for the protocols tcp, udp, and tcp/udp.

n	Specify either a single port or a range of ports - for example: 1234-1250.

n	To allow any port, use 0.

n	Separate multiple items with any of the following: a line break, a comma, or a single space.
