DESCRIPTION
Select the check box to allow or disallow the computer with the IP address that
matches the IP address(es) in the Service Control table to access the ZyWALL
CLI using this service.
You may change the server port number for a service if needed, however you must
use the same port number in order to use that service for remote management.
This specifies from which computers you can access which ZyWALL zones.
This the index number of the service control rule.
The entry with a hyphen (-) instead of a number is the ZyWALL's (non-configurable)
default policy. The ZyWALL applies this to traffic that does not match any other
configured rule. It is not an editable rule. To apply other behavior, configure a rule
that traffic will match so the ZyWALL will not have to use the default policy.
This is the zone on the ZyWALL the user is allowed or denied to access.
This is the object name of the IP address(es) with which the computer is allowed or
denied to access.
This displays whether the computer with the IP address specified above can access
the ZyWALL zone(s) configured in the Zone field (Accept) or not (Deny).
Click the Add icon in the heading row to open a screen where you can add a new
rule. Refer to Table 203 on page 530

put that rule and press [ENTER] to move the rule to the number that you typed.
