Working With Screen Objects

A Screen object controls much of the identity of a Screen. It contains information for your stealth, HA, cluster, and administrative rules. Upon installation, a Screen object that you can edit is created. As with other common objects, when you redefine a Screen object, you must specify all the parameters that you want to set; otherwise the parameters are set to default values.

To Add a Screen

To add a screen object with a previously-created certificate, using DNS and NIS for Name Service and passing routing information, type the following:

edit> add screen vorticity ADMIN_CERTIFICATE vorticity.admin RIP DNS NIS COMMENT "The screen that protects the sales office"

Note -

Adding a comment is optional.
