ZyXEL Communications 1000 User Manual

ZyWALL USG 1000 User’s Guide

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.

There is also an option that gives SIP traffic priority over all other traffic going 
through the ZyWALL. This maximizes SIP traffic throughput for improved VoIP call 
sound quality.

• Use  the  General summary screen (see 

) to enable and 

disable application patrol. 

• Use  the  Common, Instant Messenger, Peer to Peer, VoIP, and Streaming 

(see 

) screens to look at the applications the ZyWALL 

can recognize, and review the settings for each one. You can also enable and 

disable the rules for each application and specify the default and custom policies 

for each application.

• Use  the  Application Patrol Edit screen (see 

) to 

edit the settings for an application. 

• Use  the  Application Policy Edit screen (see 

edit a group of settings for an application. 

• Use  the  Other screens (see 

) to control what the 

ZyWALL does when it does not recognize the application, and it identifies the 

conditions that refine this. It also lets you open the Other Configuration Add/

Edit screen to create new conditions or edit existing ones.
