ProSafe VPN Firewall 200 FVX538 Reference Manual
3-4 LAN Configuration
v1.0, March 2009
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. Primary DNS Server. (Optional) If an IP address is specified, the VPN firewall will
provide this address as the primary DNS server IP address. If no address is specified, the
VPN firewall will provide its own LAN IP address as the primary DNS server IP address.
e. Secondary DNS Server. (Optional) If an IP address is specified, the VPN firewall will
provide this address as the secondary DNS server IP address.
f. 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.
g. Enter a Lease Time. This specifies the duration for which IP addresses will be leased to
clients.
h. To enable the DHCP server to provide LDAP server information, check the Enable LDAP
Information checkbox and fill in the fields accordingly.
i. 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.
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.
