5 DMZ
The DeMilitarized Zone (DMZ) allows public servers (web, e-mail, FTP, etc.) to be visible to the outside world
and still have firewall protection from DoS (Denial of Service) attacks.
You can assign TCP/IP configuration via DHCP to computers connected to the DMZ ports. Otherwise,
configure the computers with static IP addresses (in the same subnet as the DMZ port's IP address) and DNS
server addresses. Use the ZyWALL's DMZ IP address as the default gateway.
Do the following to configure the DMZ if the ZyWALL is in routing mode.
You do not need to configure DMZ with bridge mode, skip to
1 Click NETWORK > DMZ in the navigation panel.
2 Specify an IP address and subnet mask for the
DMZ interface.
If you use private IP addresses on the DMZ, use
NAT to make the servers publicly accessible (see
Section 6).
A public IP address must be on a separate subnet
from the WAN port's public IP address. If you do
not configure NAT for the public IP addresses on
the DMZ, the ZyWALL routes traffic to the public IP
addresses on the DMZ without performing NAT.
This may be useful for hosting servers for NAT
unfriendly applications.
3 Click Apply.
4 By default, LAN/DMZ ports 1 to 4 are all LAN ports.
To configure a port as a DMZ port, click the Port
Roles tab, select its radio button next to DMZ and
click Apply.
