• MAC-level Control over PCs. The Network Database uses the MAC address to identify each
PC or device. So changing a PC's IP address does not affect any restrictions on that PC.
• Group and Individual Control ov er PCs
– You can assign PCs to Groups and apply restrictions to each Group using the Firewall
Rules screen (see “Services-Based Rules” on page 4-2).
– You can also select the Groups to be covered by the Block Sites feature (see “Setting
Block Sites (Content Filtering)” on page 4-22).
– If necessary, you can also create Firewall Rules to apply to a single PC (see “Enabling
Source MAC Filtering” on page 4-24). Because the MAC address is used to identify each
PC, users cannot avoid these restrictions by changing their IP address.
• A computer is identified by its MAC address—not its IP address. Hence, changing a
computer’s IP addres s does not affect any restrictions applied to that PC.
The LAN Groups screen contains a list of all known PCs and network devices, as well as hosts that
are assigned dynamic IP addresses by this router.
