You can enter new policy object names, or delete names in the Endpoint field
itself. The names must be valid names of policy objects already known to the

addresses directly into this field.

convention used by Microsoft Outlook.

notation. For example, you can enter a subnet in the form 10.0.0.* or 10.0.0.0/20.

• A non-multi-cast subnet can be used only as the destination, and only in a
uni-directional policies.
• A multi-cast subnet can be used as either the source or the destination of the
traffic in a uni-directional policy.

Endpoint fields. The arrow is three-way toggle between forward, reverse, and
bi-directional.

Application selector button at the right of either Application field. This displays a
list of applications known to the Policy System.
Select an application and click OK. You can specify one application for either
endpoint.

(TCP or UDP) and a port number (for example:
TCP/111
). The form is:
UDP/<
port#>
TCP/< port#>
TCP and UDP are the two supported protocol types.
