ProSAFE Dual WAN Gigabit WAN SSL VPN Firewall FVS336Gv3

• 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 Manage the Network Database on

page 134) and apply restrictions (outbound rules and inbound rules) to each group

(see Overview of Rules to Block or Allow Specific Kinds of Traffic on page 212).

- 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

Manage Content Filtering on page 308).

- You can create firewall rules to apply to a single computer (see Enable Source MAC

Filtering on page 314). 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 View or Add Devices

Manually to the Network Database on page 135. For information about how to display saved

bindings, see View and Set Up an IPv4/MAC Binding on page 318 and View and Set Up

IPv6/MAC Bindings on page 322.

Manage the Network Database

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

database entries.

The following sections provide information about managing the network database:

• View or Add Devices Manually to the Network Database

• Change Device Settings Manually in the Network Database
