ProSecure Unified Threat Management (UTM) Appliance Reference Manual
Using the Setup Wizard to Provision the UTM in Your Network 2-9
v1.0, January 2010
Table 2-1. Setup Wizard Step 1: LAN Settings
Setting Description (or Subfield and Description)
LAN TCP/IP Setup
IP Address Enter the IP address of the UTM’s default VLAN (the factory default is
192.168.1.1).
Note: Always make sure that the LAN port IP address and DMZ port IP address
are in different subnets.
Note: If you change the LAN IP address of the UTM‘s default VLAN while being
connected through the browser, you will be disconnected. You must then open a
new connection to the new IP address and log in again. For example, if you
change the default IP address from 192.168.1.1 to 10.0.0.1, you must now enter
https://10.0.0.1 in your browser to reconnect to the Web Management
Interface.
Subnet Mask Enter the IP subnet mask. The subnet mask specifies the network number
portion of an IP address. The UTM automatically calculates the subnet mask
based on the IP address that you assign. Unless you are implementing
subnetting, use 255.255.255.0 as the subnet mask (computed by the UTM).
DHCP
Disable DHCP Server If another device on your network is the DHCP server for the default VLAN, or if
you will manually configure the network settings of all of your computers, select
the Disable DHCP Server radio button to disable the DHCP server. This is the
default setting.
Enable DHCP Server Select the Enable DHCP Server radio button to enable the UTM to function as
a Dynamic Host Configuration Protocol (DHCP) server, providing TCP/IP
configuration for all computers connected to the default VLAN. Enter the
following settings:
Domain Name This is optional. Enter the domain name of the UTM.
Starting IP
Address
Enter the starting IP address. This address specifies the first of
the contiguous addresses in the IP address pool. Any new
DHCP client joining the LAN is assigned an IP address
between this address and the Ending IP Address. The IP
address 192.168.1.2 is the default start address.
Ending IP
Address
Enter the ending IP address. This address specifies the last of
the contiguous addresses in the IP address pool. Any new
DHCP client joining the LAN is assigned an IP address
between the Starting IP address and this IP address. The IP
address 192.168.1.100 is the default ending address.
Note: The starting and ending DHCP IP addresses should be
in the same “network” as the LAN TCP/IP address of the UTM
(the IP address in LAN TCP/IP section above).
