Manage IPv4 Groups and Hosts (IPv4 LAN Groups)

• Manage the Network Database

• Change Group Names in the Network Database

• Set Up DHCP Address Reservation

The Known PCs and Devices table on the LAN Groups (IPv4) screen (see Figure 5

2 on

page 93) contains a list of all known computers and network devices that are assigned

dynamic IP addresses by the 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.

• Sca

nning 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 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.
