User manual ZYXEL USG 1000 QUICK GUIDE

[. . . ] · It is highly recommended you read Chapter 6 on page 93 for detailed information on essential terms used in the ZyWALL, what prerequisites are needed to configure a feature and how to use that feature. · It is highly recommended you read Chapter 7 on page 117 for ZyWALL application examples. · Subsequent chapters are arranged by menu item as defined in the Web Configurator. Read each chapter carefully for detailed information on that menu item. [. . . ] 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. 32. 1. 1 What You Can Do in this Chapter · Use the General summary screen (see Section 32. 2 on page 573) to enable and disable application patrol. · Use the Common, Instant Messenger, Peer to Peer, VoIP, and Streaming (see Section 32. 3 on page 574) 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 Section 32. 3. 1 on page 575) to edit the settings for an application. · Use the Application Policy Edit screen (see Section 32. 3. 2 on page 579) to edit a group of settings for an application. · Use the Other screens (see Section 32. 4 on page 582) 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. ZyWALL USG 100/200 Series User's Guide 563 Chapter 32 Application Patrol 32. 1. 2 What You Need to Know If you want to use a service, make sure both the firewall and application patrol allow the service's packets to go through the ZyWALL. Note: The ZyWALL checks firewall rules before it checks application patrol rules for traffic going 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. Configurable Application Policies The ZyWALL has policies for individual applications. For each policy, you can specify the default action the ZyWALL takes once it identifies one of the service's connections. · Outbound traffic goes from a LAN1 zone device to a WAN zone device. Bandwidth management is applied before sending the packets out a WAN zone interface on the ZyWALL. · Inbound traffic comes back from the WAN zone device to the LAN1 zone device. Bandwidth management is applied before sending the traffic out a LAN1 zone interface. Figure 409 LAN1 to WAN Connection and Packet Directions LAN1 Connection Outbound BWM BWM Inbound Outbound and Inbound Bandwidth Limits You can limit an application's outbound or inbound bandwidth. This limit keeps the traffic from using up too much of the out-going interface's bandwidth. When you apply a bandwidth limit to outbound or inbound traffic, each member of the out-going zone can send up to the limit. The connection initiator is on the LAN1 so outbound means the traffic traveling from the LAN1 to the WAN. Each of the WAN zone's two interfaces can send the limit of 200 kbps of traffic. 566 ZyWALL USG 100/200 Series User's Guide Chapter 32 Application Patrol · Inbound traffic is limited to 500 kbs. The connection initiator is on the LAN1 so inbound means the traffic traveling from the WAN to the LAN1. Figure 410 LAN1 to WAN, Outbound 200 kbps, Inbound 500 kbps Outbound 200 kbps Outbound 200 kbps Inbound 500 kbps Bandwidth Management Priority · The ZyWALL gives bandwidth to higher-priority traffic first, until it reaches its configured bandwidth rate. · The ZyWALL uses a fairness-based (round-robin) scheduler to divide bandwidth among traffic flows with the same priority. · The ZyWALL automatically treats traffic with bandwidth management disabled as priority 7 (the lowest priority). Maximize Bandwidth Usage Maximize bandwidth usage allows applications with maximize bandwidth usage enabled to "borrow" any unused bandwidth on the out-going interface. [. . . ] If this device does cause harmful interference to radio/television reception, which can be determined by turning the device off and on, the user is encouraged to try to correct the interference by one or more of the following measures: 1 2 3 Reorient or relocate the receiving antenna. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. 4 FCC Radiation Exposure Statement · This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. ! 1128 ZyWALL USG 100/200 Series User's Guide Appendix G Legal Information Notices Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.
