Manage The Network Database - NETGEAR SRX5308 Reference Manual

Some advantages of the network database are:
• Generally, you do not need to enter either IP address or MAC addresses. Instead, you
can just select the name of the desired computer or device.
• There is no need to reserve an IP address for a computer in the DHCP server. All IP
address assignments made by the DHCP server are maintained until the computer or
device is removed from the network database, either by expiration (inactive for a long
time) or by you.
• There is no need to use a fixed IP address on a computers. Because the IP address
allocated by the DHCP server never changes, you do not need to assign a fixed IP
address to a computer to ensure that it always has the same IP address.
• A computer is identified by its MAC address—not by its IP address. The network
database uses the MAC address to identify each computer or device. Therefore,
changing a computer's IP address does not affect any restrictions applied to that
computer.
• Control over computers can be assigned to groups and individuals:
- You can assign computers to groups (see
page) and apply restrictions (LAN WAN outbound rules, LAN DMZ outbound rules,
LAN WAN inbound rules, and LAN DMZ inbound rules) to each group (see
to Block or Allow Specific Kinds of Traffic
- If necessary, you can also create firewall rules to apply to a single computer (see
Enable Source MAC Filtering
identify each computer, users cannot avoid these restrictions by changing their IP
address.
