Service Ports
Service ports are used when setting up filter segments on 
the network (the range of IP addresses/netmasks to be 
detected by the ProxyBlocker), the global (default) filtering 
profile, and the minimum filtering level.
When setting up the range of IP addresses/netmasks to be 
detected, service ports can be set up to be open (ignored). 
When creating the global filtering profile and the minimum 
filtering level, service ports can be set up to be blocked or 
filtered.
Examples of service ports that can be set up include File 
Transfer Protocol (FTP), Hyper Text Transfer Protocol 
(HTTP), Network News Transfer Protocol (NNTP), Secured 
HTTP Transmission (HTTPS), and Secure Shell (SSH).
Rules
A rule is comprised of library categories to block, leave 
open, assign a warn setting, or include in a white list. 
Access to an open library category can be restricted to a set 
number of minutes. Each rule that is created by the global 
administrator is assigned a number. A rule is selected when 
creating a filtering profile for an entity.
Minimum Filtering Level
The minimum filtering level consists of library categories set 
up at the global level to be blocked or opened, and service 
ports set up to be blocked or filtered. If the minimum filtering 
level is created, it applies to all users in IP groups, and takes 
precedence over filtering settings made for group and user 
filtering profiles.
The minimum filtering level does not apply to any user who 
does not belong to a group, and to groups that do not have 
a filtering profile established.
