ZoneAlarm Features
MUVPN Client Guide 41
Use the block servers checkbox for each zone to prevent all programs
from acting as servers for that zone. By checking this option, no
application will be allowed to listen for incoming connections in that
zone, even if you've checked the Allow Server option in the Programs
panel.
Definition of Zones
ZoneAlarm divides traffic into two separate zones: the Local Zone and the
Internet Zone.
The purpose of the Local Zone is to enable ZoneAlarm to recognize what
you as the user, deem as permissible traffic.
The Local Zone is made up of the computers and resources you have
defined as trusted. These are usually resources on your local network but
they can include any resource of your choosing. Use the Advanced button
on the Security panel to define and modify the components of the Local
Zones.
