Setting Description
Name Enter the name of the computer or device.
IP Address Type From the drop-down list, select how the computer or device receives its IP address:
• Fixed (set on PC). The IP address is statically assigned on the computer or
device.
• Reserved (DHCP Client). Directs the UTM’s DHCP server to assign the
specified IP address always to this client during the DHCP negotiation (see Set
Up Address Reservation on page 116).
Note: When you assign a reserved IP address to a client, the selected IP address
needs to be outside the range of addresses allocated to the DHCP server pool.
IP Address In the IP Address field, enter the IP address that this computer or device is
assigned. If the IP address type is Reserved (DHCP Client), the UTM reserves the
IP address for the associated MAC address.
MAC Address Enter the MAC address of the computer’s or device’s network interface. The MAC
address format is six colon-separated pairs of hexadecimal characters (0–9 and
A–F), such as 01:23:45:67:89:AB.
Group From the drop-down list, select the group to which the computer or device is
assigned. (Group 1 is the default group.)
