ProSafe VPN Firewall 200 FVX538 Reference Manual
LAN Configuration 3-3
v1.0, August 2006
4. Check the Enable DHCP Server radio button. By default, the router will function as a DHCP
(Dynamic Host Configuration Protocol) server, providing TCP/IP configuration for all
computers connected to the router's LAN. If another device on your network will be the DHCP
server, or if you will manually configure all devices, check the Disable DHCP Server radio
button. Enable DHCP Server is the default. If Enabled is selected, enter the following
parameters:
a. Enter the Domain Name of the router (this is optional).
b. 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 will be assigned an IP
address between this address and the Ending IP Address. The IP address 192.168.1.2 is the
default start address.
c. 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 will be 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.
d. Enter a WINS Server IP address. This box can specify the Windows NetBios Server IP if
one is present in your network. This field is optional.
e. Enter a Lease Time. This specifies the duration for which IP addresses will be leased to
clients.
f. Check the Enable DNS Proxy radio box. This is optional—the default is enabled. If
enabled, the VPN firewall will provide a LAN IP Address for DNS address name
resolution.
5. Click Apply to save your settings.
Note: The Starting and Ending DHCP addresses should be in the same “network”
as the LAN TCP/IP address of the router (the IP Address in LAN TCP/IP
Setup section).
Note: If you change the LAN IP address of the firewall while 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 192.168.1.1 to 10.0.0.1, you must enter http://10.0.0.1 in your browser
to reconnect to the web management interface.
