2. Click 'OK' to save the settings.
3. Verify that remote administration is enabled, by accessing Watson's WBM from a
WAN PC.
To define a port forwarding rule, perform the following:
1. From a LAN PC, browse to Watson's WBM and select the 'Firewall' menu item
under the 'Services' tab. In the links bar, select 'Port Forwarding', and click 'New
Entry'.
2. In the 'Local Host' field, enter the server's LAN PC name or IP address. In the
'Protocol' drop-down menu, select the 'HTTP' protocol.
3. Click 'OK' to save the settings.
4. To verify that port forwarding takes place, access Watson's WBM from a WAN
PC. You should be redirected to the LAN HTTP server.
You may disable the port forwarding rule by deselecting its check box in the 'Port
Forwarding' screen. If you try to access the local server from the WAN, the HTTP
server will not be accessible, and Watson's WBM 'Home' page will appear instead.
8.2.4 DMZ Host
The DMZ (Demilitarized) Host feature allows one local computer to be exposed to
the Internet. Designate a DMZ host when:
 You wish to use a special-purpose Internet service, such as an on-line game or
video-conferencing program, that is not present in the Port Forwarding list and
for which no port range information is available.
 You are not concerned with security and wish to expose one computer to all
services without restriction.
Warning: A DMZ host is not protected by the firewall and may be vulnerable to attack.
Designating a DMZ host may also put other computers in the home network at risk.
When designating a DMZ host, you must consider the security implications and pro-
tect it if necessary.
