Chapter 19 Bandwidth Management
Enable Bandwidth
Filter
Select Enable Bandwidth Filter to have the ZyWALL use this bandwidth 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 the Enable
Bandwidth Filter check box).
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 standard 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.
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.
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).
