Manage The Network Database - NETGEAR ProSafe SRX5308 Reference Manual

• There is no need to reserve an IP address for a PC in the DHCP server. All IP address
assignments made by the DHCP server are maintained until the PC 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 PCs. Because the IP address allocated
by the DHCP server never changes, you do not need to assign a fixed IP address to a PC
to ensure that it always has the same IP address.
• A PC is identified by its MAC address—not by its IP address. The network database uses
the MAC address to identify each PC or device. Therefore, changing a PC's IP address
does not affect any restrictions applied to that PC.
• Control over PCs can be assigned to groups and individuals:
- You can assign PCs to groups (see
this 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
Rules to Block or Allow Specific Kinds of Traffic
- If necessary, you can also create firewall rules to apply to a single PC (see
Source MAC Filtering
each PC, users cannot avoid these restrictions by changing their IP address.
