display a summary of the rule that you just added.
Figure 8-11: Port Forwarding Rule
You may edit the port forwarding rule by clicking its entry under the 'Local Host'
column in the 'Port Forwarding' screen. You can disable the rule in order to make a
service unavailable without having to remove the rule from the 'Port Forwarding'
screen. This may be useful if you wish to make the service unavailable only tempo-
rarily and expect that you will want to reinstate it in the future.
To temporarily disable a rule, clear the check box next to the service name.
To reinstate it at a later time, simply reselect the check box.
To remove a rule, click the action icon for the service. The service will be
permanently removed.

the network initiates the connection—for example, opens an FTP connection with
an FTP server on the Internet. But only one computer can serve as a server, re-
sponding to requests from computers on the Internet.
8.2.3.1 A Port Forwarding Example
In order to allow outside access (from the WAN) to a server inside your LAN, you
must configure Watson's firewall, by adding a port forwarding rule. The following
exercise demonstrates how to allow such access to an HTTP server located inside
Watson's LAN.
When remote administration is enabled on Watson, an attempt to browse to Wat-
son's WBM from a WAN PC will yield the WBM's 'Home' page. However, when the
following port forwarding rule is defined on Watson, an attempt to browse to Wat-
son's WBM from a WAN PC will yield the HTTP server located on the LAN.
To enable remote administration, perform the following:
