Application Patrol
This chapter describes how to set up application patrol for the ZyWALL. 
20.1  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.
Note: 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.
20.2  Application Patrol Commands Summary
