Game Rules List

The section shows the currently defined game rules. A game rule can be changed by

clicking the Edit icon, or deleted by clicking the Delete icon. When you click the Edit

icon, the item is highlighted, and the "Edit Game Rule" section is activated for

editing.

The StreamEngine feature helps improve your network gaming performance by prioritizing

the data flows of network applications.

StreamEngine Setup

Enable StreamEngine

Enable this option for better performance and experience with online games

and other interactive applications, such as VoIP.

Automatic Classification

This option is enabled by default so that your router will automatically determine

which programs should have network priority.

Dynamic Fragmentation

This option should be enabled when you have a slow Internet uplink. It helps to

reduce the impact that large low priority network packets can have on more

urgent ones by breaking the large packets into several smaller packets.

Automatic Uplink Speed

When enabled, this option causes the router to automatically measure the

useful uplink bandwidth each time the WAN interface is re-established (after a

reboot, for example).

Measured Uplink Speed

This is the uplink speed measured when the WAN interface was last

re-established. The value may be lower than that reported by your ISP as it

does not include all of the network protocol overheads associated with your

ISP's network. Typically, this figure will be between 87% and 91% of the stated

uplink speed for xDSL connections and around 5 kbps lower for cable network

connections.

Manual Uplink Speed

If Automatic Uplink Speed is disabled, this options allows you to set the uplink

speed manually. Uplink speed is the speed at which data can be transferred

from the router to your ISP. This is determined by your ISP. ISPs often specify

speed as a downlink/uplink pair; for example, 1.5Mbps/284kbps. For this

example, you would enter "284". Alternatively you can test your uplink speed

with a service such as

www.dslreports.com

. Note however that sites such as

DSL Reports, because they do not consider as many network protocol

overheads, will generally note speeds slightly lower than the Measured Uplink

Speed or the ISP rated speed.

Connection Type

By default, the router automatically determines whether the underlying

connection is an xDSL/Frame-relay network or some other connection type

(such as cable modem or Ethernet), and it displays the result as

Detected

xDSL or Frame Relay Network

. If you have an unusual network connection in

which you are actually connected via xDSL but for which you configure either

"Static" or "DHCP" in the WAN settings, setting this option to

xDSL or Other

Frame Relay Network

ensures that the router will recognize that it needs to

shape traffic slightly differently in order to give the best performance. Choosing

xDSL or Other Frame Relay Network

causes the measured uplink speed to be

39

reported slightly lower than before on such connections, but gives much better

results.

StreamEngine Rules

A StreamEngine Rule identifies a specific message flow and assigns a priority to that

flow. For most applications, automatic classification will be adequate, and specific

StreamEngine Rules will not be required.

Conflicting rules are not permitted. Conflicting rules are those that share any

combination of source address/port, destination address/port, and protocol. Rejecting

conflicting rules ensures that every flow defined in a rule receives the expected

priority and avoids indeterminate prioritization that could reduce QoS effectiveness.

Name

Create a name for the rule that is meaningful to you.

Priority

The priority of the message flow is entered here -- 1 receives the highest priority

(most urgent) and 255 receives the lowest priority (least urgent). Priority 0 is

reserved. Flows that are not prioritized by any rule receive lowest priority.

Protocol

The protocol used by the messages. The common choices can be selected from

the drop-down menu. To specify any other protocol, enter its protocol number

(

as assigned by the IANA

) in the

Protocol

box.

Source IP Range

The rule applies to a flow of messages whose LAN-side IP address falls within

the range set here.

Source Port Range

The rule applies to a flow of messages whose LAN-side port number is within

the range set here.

Destination IP Range

The rule applies to a flow of messages whose WAN-side IP address falls within

the range set here.

Destination Port Range

The rule applies to a flow of messages whose WAN-side port number is within

the range set here.
