Network Database
The VPN firewall contains a list of all computers and network devices to which it assigned
dynamic IP addresses or that it discovered by other means. This list also contains all
computers and network devices for which you entered IP addresses manually. Collectively,
these entries make up the network database.
The network database is updated by these methods:
DHCP client requests. When the DHCP server is enabled, it accepts and responds to
DHCP client requests from computers and other network devices. These requests also
generate an entry in the network database. This is an advantage of enabling the DHCP
server feature.
Scanning the network. The local network is scanned using Address Resolution Protocol
(ARP) requests. The ARP scan detects active devices that are not DHCP clients.
However, if the VPN firewall receives a reply to an ARP request from a device with an
active firewall that blocks the device name, the VPN firewall might not be able to
determine the device name.
Note: In large networks, scanning the network might generate unwanted traffic.
Manual entry. You can manually enter information about a network device.
A network database has the following advantages:
Generally, you do not need to enter an IP address or a MAC address. Instead, you can
select the name of the desired computer or device.
