Set Up Address Reservation

The Known PCs and Devices table on the LAN Groups screen (see Figure 59 on page 113) contains a list of all known computers and network devices that are assigned dynamic IP addresses by the UTM, or have been discovered by other means. 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 UTM 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.
