•

Network Database
The Network Database is an automatically-maintained list of all known PCs and network devices.
PCs and devices become known by the following methods:
•
DHCP Client Requests
By default, the DHCP server in this Router is enabled, and will accept and respond to DHCP
client requests from PCs and other network devices. These requests also generate an entry in
the Network Database. Because of this, leaving the DHCP Server feature (on the LAN screen)
enabled is strongly recommended.
•
Scanning the Network
The local network is scanned using standard methods such as ARP and NetBIOS. This will
detect active devices which are not DHCP clients. However, sometimes the name of the PC or
device cannot be accurately determined, and will be shown as Unknown.
•
User Input
If necessary, you can manually input details of PCs or other network devices. This is necessary
if the PC or devices is not yet attached to the network, or is on another LAN segment.

Advantages of the Network Database
•
Generally, you do not need to enter either IP address or MAC addresses.
•
Instead, you can just select the desired PC or device.
•
No need to reserve an IP address for a PC in the DHCP Server.
All IP address assignments made by the DHCP Server will be maintained until the PC or
device is removed from the database, either by expiry (inactive for a long time) or by you.
•
No need to use a Fixed IP on PCs
Because the address allocated by the DHCP Server will never change, you don't need to assign
a fixed IP to a PC to ensure it always has the same IP address.
•
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 & Individual Control over PCs
You can assign PCs to Groups, and apply restrictions to each Group, using the Firewall Rules
screen.
•
You can also select the Groups to be covered by the Block Sites feature.
•
If necessary, you can also create Firewall Rules to apply to a single PC.
•
Because the MAC address is used to identify each PC, users cannot avoid these
restrictions by changing their IP address.
