Access Control
Overview
The Access Control feature allows administrators to restrict Internet Access by individual PCs.
The process uses "Packet Filtering" to block or discard data packets. By default, no packets are
blocked or discarded.
The system works as follows:
•
Access restrictions are imposed on "Groups" (of PCs), not on individual users.
•
Groups are pre-named "Default", "Group 1", "Group 2", "Group 3", and "Group 4". These
names can not be changed.
•
All PCs are in the "Default" Group, unless explicitly moved to another group.
•
Access restrictions may be imposed on any Group, including the "Default" group.
