Rate Type: 2 types are provided:

 Limited (Maximum): specify a limited data rate for this policy. It also is the maximal

rate for this policy. As above FTP server example, you may want to “throttle” the outgoing

FTP speed to 20% of 256K and limit to it, you may use this type.

 Guaranteed (Minimum): specify a minimal data rate for this policy. For example,

you want to provide a guaranteed data rate for your outside customers to access your

internal FTP server with, say at least, 20% of your total bandwidth. You can use this type.

Then, if there is available bandwidth that is not used, it will be given to this policy by

following priority assignment.

Ratio: Assign the data ratio for this policy to be controlled. For examples, we want to

only allow 20% of the total data transfer rate for the LAN-to-WAN direction to be used for

FTP server. Then we can specify here with data ratio = 20. If you have ADSL LINE with

256K/bps.rate, the estimated data rate, in kbps, for this rule is 20%*256*0.9 = 46kbps.

(For 0.9 is an estimated factor for the effective data transfer rate for a ADSL LINE from LAN

to WAN. For WAN-to-LAN, it is 0.85 to 0.8).

Priority: Specify the priority for the bandwidth that is not used. For examples, you may

specify two different QoS policies for different applications. Both applications need a

minimal bandwidth and need more bandwidth, beside the assigned one, if there is any

available/non-used one available. So, you may specify which application can have higher

priority to acquire the non-used bandwidth.

 High

 Normal: The default is normal priority.

 Low

For the sample priority assignment for different policies, it is served in a First-In-First-Out

way.

Internal IP Address: The IP address values for Local LAN machines you want to

control. (For IP packets from LAN to WAN, it is the source IP address. For IP packages from

WAN to LAN, it is the destination IP address.)

Internal Port: The Application port values for local LAN machines you want to control.

(For TCP/UDP packets from LAN to WAN, it is the source port value. For TCP/UDP packets
