DESCRIPTION

 

 

Enable Bandwidth

Select Enable Bandwidth Filter to have the ZyWALL use this bandwidth filter

Filter

when it performs bandwidth management.

 

You must enter a value in at least one of the following fields (other than the

 

Subnet Mask fields which are only available when you enter the destination or

 

source IP address).

Service

This field simplifies bandwidth class configuration by allowing you to select a

 

predefined application. When you select a predefined application, you do not

 

configure the rest of the bandwidth filter fields (other than enabling or disabling

 

the filter).

 

FTP (File Transfer Program) is a program to enable fast transfer of files,

 

including large files that may not be possible by e-mail. Select FTP from the

 

drop-down list box to configure the bandwidth filter for FTP traffic.

 

H.323 is a protocol used for multimedia communications over networks, for

 

example NetMeeting. Select H.323 from the drop-down list box to configure the

 

bandwidth filter for H.323 traffic.

 

Note: If you select H.323, make sure you also use the ALG

 

screen to turn on the H.323 ALG.

 

SIP (Session Initiation Protocol) is a signaling protocol used in Internet

 

telephony, instant messaging, events notification and conferencing. The

 

ZyWALL supports SIP traffic pass-through. Select SIP from the drop-down list

 

box to configure this bandwidth filter for SIP traffic. This option makes it easier

 

to manage bandwidth for SIP traffic and is useful for example when there is a

 

VoIP (Voice over Internet Protocol) device on your LAN.

 

Note: If you select SIP, make sure you also use the ALG screen

 

to turn on the SIP ALG.

 

Select Custom from the drop-down list box if you do not want to use a

 

predefined application for the bandwidth class. When you select Custom, you

 

need to configure at least one of the following fields (other than the Subnet

 

Mask fields which you only enter if you also enter a corresponding destination

 

or source IP address).

Destination IP

Enter the source subnet mask. This field is N/A if you do not specify a Source

 

IP Address. Refer to Appendix E on page 690 for more information on IP

 

subnetting.

Enter the port number of the source. See the following table for some common

 

services and port numbers.
