Specifications

11
IP Address − this is the IP address that will be assigned to the DMZ port. The default is
10.1.1.254 with a subnet mask of 255.255.255.0.
Subnet Mask − this is the subnet mask corresponding to the DMZ port’s IP address,
above. The default is 255.255.255.0.
The IP address assigned to the DFL-900 here, must be on the same subnet (be within
the same IP address range) specified on the DHCP Servers. The DHCP Server fields
allow you to configure the DFL-900 to be a DHCP Server on your DMZ. The DFL-900
can then automatically assign IP addresses, subnet masks, default gateway and DNS
server addresses to computers on your LAN. The computers on your DMZ must have a
DHCP client enabled to get their network address information from the DFL-900.
IP Pool Starting Address − the first IP address of the range from which the DFL-900
will assign to each of the computers on your DMZ.
Pool Size − the number of IP addresses which the DFL-900 will assign to the
computers on you DMZ.
Virtual Server Settings
Virtual Servers are computers connected using the DMZ port. They act as servers to
provide services to your LAN port or other Internet users on the WAN port. The Virtual
Server setting page maps one global IP address − an IP address that is valid on the
Internet, usually assigned by your ISP − to one local IP address from the IP address
range assigned to the DFL-900’s DMZ port. The default DMZ IP address is 10.1.1.254,
so the servers’ IP must range from 10.1.1.1 to 10.1.1.253, with a subnet mask of
255.255.255.0.
