Figure 35-6. Gateway Settings .. Device Groups Window
Device Groups enable configuration settings to be associated with an arbitrary list of devices with
disjoint IP addresses, as opposed to address ranges and wild cards which can only refer to
contiguous IP address spaces.
The Add button displays a new window which is used to create a new Device Group. Once the
Device Group has been created, additional addresses may be added under the Address column. The
Organize button can be used to reorder the list of addresses in numerical ascending order.
To modify the name of a Device Group, right-click on the group name in the Device Group list,
and click Modify. To remove a Device Group, right-click on the group name in the Device Group
list, and click Delete.
Due to the frequency that addresses will be queried by other system services, the Ranger Gateway
maintains a cache of Device Group information to increase system performance at the cost of
memory usage. The Device Groups Cache Size is used to set the maximum number of entries in
the cache. The default is 100 entries with a valid range of 0 – 10000.
Gateway Settings...Forwarding
The Gateway Settings...Forwarding window provides the configuration information for the
Ranger Gateway handling of forwarding requests.
