CHAPTER 37
Application Patrol
This chapter describes how to set up application patrol for the Zyxel Device.
37.1 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 Zyxel Device checks firewall rules before application patrol rules for traffic going
through the Zyxel Device. To use a service, make sure both the firewall and application
patrol allow the service’s packets to go through the Zyxel Device.
Application patrol examines every TCP and UDP connection passing through the Zyxel Device and
identifies what application is using the connection. Then, you can specify, by application, whether or
not the Zyxel Device continues to route the connection.
