Enable

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.

Server Port

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.

Service Control

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.

Zone

This is the zone on the ZyWALL the user is allowed or denied to access.

Address

This is the object name of the IP address(es) with which the computer is allowed or 
denied to access.

Action

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).
