This chapter describes how to set up application patrol for the ZyWALL.
19.1 Application Patrol Overview
Application patrol provides a convenient way to manage the use of various applications on the
network. It manages general protocols (for example, http and ftp) and instant messenger (IM),
peer-to-peer (P2P), Voice over IP (VoIP), and streaming (RSTP) applications. You can even
control the use of a particular application's individual features (like text messaging, voice,
video conferencing, and file transfers). Application patrol also has powerful bandwidth
management including traffic prioritization to enhance the performance of delay-sensitive
applications like voice and video.
The ZyWALL checks firewall rules before application patrol rules for traffic
going through the ZyWALL. To use a service, make sure both the firewall and
application patrol allow the service's packets to go through the ZyWALL.
Application patrol examines every TCP and UDP connection passing through the ZyWALL
and identifies what application is using the connection. Then, you can specify, by application,
whether or not the ZyWALL continues to route the connection.
