Field Description
Enable Group Based
System Access Control
When this box is checked, the rules for IP based access are enforced. They
are ignored when the box is not checked.
Default Action If after evaluation of all rules a request for connection from a given IP
address has not had either an Accept or Drop decision made, this selection
can allow it to be either Accepted or Dropped. In other words, this drop-down
defines the default action for IP addresses with no rules defined.
Rule creation and
editing
Spiders come from the factory with one rule defined as an example of the
rule structure: Rule 1 allows all groups access from source IP 0.0.0.0 to
255.255.255.255. Additional rules may be entered in the edit boxes.
 Rule Number: Defines where in the evaluation sequence this rule is to
be applied.
 Starting and Ending IP Addresses: Define the range over which the
rule applies.
 Group: Defines which user group is affected by this rule. Built-in
groups include Admin, All, and Unknown (no group assigned). As
additional groups are defined in User ManagementUsers
Group Management, they will appear in the drop-down. A rule can
apply to only one group at a time.
 Action: Chooses whether this is to be a Drop or Accept rule.
 After a rule has been defined, it needs to go in the correct place in the
list.
 Append: Puts the rule at the end of the list. The rule number changes
to reflect the last position on the list.
 Insert: Puts the rule in the place on the list indicated by the rule
number, renumbering and moving down the other rules to make room.
 Replace: Deletes the previous rule of that number and replaces it with
the new rule.
 Delete: Deletes the rule of that number and moves the others up. Note
that for a Delete, the fields other than the rule number do not need to
be filled in.
