DHCPv6 Server Options
The Known PCs and Devices table on the LAN Groups (IPv4) screen (see
page 68) contains a list of all known computers and network devices that are assigned
dynamic IP addresses by the wireless VPN firewall, have been discovered by other means,
or were entered 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.
Note:
In large networks, scanning the network might generate unwanted
traffic.
Note:
When the wireless VPN firewall receives a reply to an ARP request,
it might not be able to determine the device name if the software
firewall of the device blocks the name.
•
Manual entry. You can manually enter information about a network device.
These are some advantages of the network database:
•
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.
•
There is no 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.
