Netgear FVS318N 사용자 설명서

There is no need to use a fixed IP address on a computer. 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 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 

on this 

page) and apply restrictions (outbound rules and inbound rules) to each group (see 

You can select groups that are allowed access to URLs that you have blocked for 
other groups, or the other way around, block access to URLs that you have allowed 
access to for groups (see 

If necessary, you can also create firewall rules to apply to a single computer (see 

on page 183). Because the MAC address is used to 

identify each computer, users cannot avoid these restrictions by changing their IP 
address.

Manage the Network Database

You can view the network database, manually add or remove database entries, and edit 
database entries.

To view the network database, select Network Configuration > LAN Setup > LAN Groups. 
The LAN Groups screen displays. (The following figure shows some manually added devices 
in the Known PCs and Devices table as an example.)
