IP groups enable easier definition of packet filter rules. These groups can be used for specification of the Remote entry in the dialog for packet filter rule definition (see above).
IP groups can be viewed and defined in the IP Group tab of the Advanced Packet Filter window.
The window consists of the two following columns:
Group name — name of an IP group. Use the plus button to view a list of all items included in a particular group
Definition — definitions of individual items of a particular group
Uncheck an item to disable a rule temporarily. This can be helpful for example when testing or debugging — it is not necessary to remove items and then define them again.
Click on the button (or the button to edit a selected item) to open a dialog for IP group definition.
- Is enabled
Check/uncheck this option to enable/disable the item. This option is identical to the matching field next to the item name in the IP Groups tab (see above). If the Is enabled is unchecked, the item is not active. This means that it is not included in the group.
- Group name
Name of the group to which the item will be included. Specify the item by one of the following methods:
select a name from the menu — the item will be added to this group
enter a new group name — this group will be created automatically and the item will be added to the new group
- Type
Type of the new item:
Host — IP address of one computer
Address range — define First address and Last address to specify IP range
Address / mask — subnet defined by an IP address and mask
Address group — another IP address group (IP addresses can be embedded into each other)
