Dhcp Address Reservation; Manage The Network Database - NETGEAR ProSafe FVS336Gv2 Reference Manual

ProSAFE Dual WAN Gigabit WAN SSL VPN Firewall FVS336Gv2
• You do not 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.
• You do not need to use a fixed IP address on a computer. Because the IP addresses that
are allocated by the DHCP server never change, 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.
• You can assign control over computers to groups and individuals:
- You can assign computers to groups (see
page 133) and apply restrictions (outbound rules and inbound rules) to each group
(see Overview of Rules to Block or Allow Specific Kinds of Traffic
- 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
- You can create firewall rules to apply to a single computer (see
Filtering on page 312). Because the MAC address is used to identify each computer,
users cannot avoid these restrictions by changing their IP address.

DHCP Address Reservation

When you specify a reserved IP address for a device on the LAN and bind that IP address to
the MAC address of the device, that device always receives the same IP address each time it
accesses the VPN firewall's DHCP server. Assign reserved IP addresses to servers and
access points that require permanent IP address settings.
A reserved IP address must be outside of the DHCP server pool. A reserved address is not
assigned until the next time the device contacts the VPN firewall's DHCP server. You can
force the device to contact the VPN firewall's DHCP server by rebooting the device or by
releasing and renewing the DHCP connection of the device.
For information about setting up address reservation with a binding, see
