without performing NAT. This may be useful for hosting servers for NAT unfriendly applica-
tions.
If the DMZ computers use private IP addresses, use NAT if you want to make them publicly
accessible.
DHCP
Like the LAN, the LAN-Cell can also assign TCP/IP configuration via DHCP to computers
connected to the DMZ ports.
See Section 4.3 on page 83 for more information on DHCP.
IP Alias
See Section 4.4 on page 84 for more information on IP alias.
Port Roles
See Section 4.5 on page 86 for more information on port roles.
6.1.3 DMZ Public IP Address Example
The following figure shows a simple network setup with public IP addresses on the WAN and
DMZ and private IP addresses on the LAN. Lower case letters represent public IP addresses
(like a.b.c.d for example). The LAN port and connected computers (A through C) use private
IP addresses that are in one subnet. The DMZ port and connected servers (D through F) use
public IP addresses that are in another subnet. The public IP addresses of the DMZ and WAN
ports are in separate subnets.
