Manage IPv4 Groups and Hosts (IPv4 LAN Groups)

The Known PCs and Devices table on the LAN Groups (IPv4) screen (see
page 60) contains a list of all known PCs 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 PCs 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
just select the name of the desired PC or device.
• 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 PC. 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.
