Chapter 20 Bandwidth Management

Table 133 ADVANCED > BW MGMT > Class Setup > Add Sub-Class (continued)

LABEL

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 TCP packets with a port

 

21 destination.

 

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 TCP packets with a port 1720 destination.

 

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 UDP packets with a port 5060

 

destination. 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 Address

Do you want your rule to apply to packets coming going to a particular (single)

Type

IP, a range of IP addresses (for example 192.168.1.10 to 192.169.1.50) or a

 

subnet? Select Single Address, Range Address or Subnet Address.

 

 

Destination IP

Enter the single IP address or the starting IP address in a range here.

Address

 

 

 

Destination End

If you are configuring a range of IP addresses, enter the ending IP address

Address / Subnet

here. If you are configuring a subnet of addresses, enter the subnet mask here.

Mask

Refer to Appendix C on page 729 for more information on IP subnetting.

 

 

Destination Port

Enter the starting and ending destination port numbers. Enter the same port

 

number in both fields to specify a single port number. See Appendix D on page

 

737 for a table of services and port numbers.

 

 

Source Address Type

Do you want your rule to apply to packets coming from a particular (single) IP,

 

a range of IP addresses (for example 192.168.1.10 to 192.169.1.50) or a

 

subnet? Select Single Address, Range Address or Subnet Address.

 

 

Source IP Address

Enter the single IP address or the starting IP address in a range here.
