Instead of entering a name for the Special Application rule, you can select from this list of 
common applications, and the remaining configuration values will be filled in accordingly.   
Trigger Port Range   
Enter the outgoing port range used by your application (for example 6500-6700).  
Trigger Protocol   
Select the outbound protocol used by your application (for example Both).  
Input Port Range   
Enter the port range that you want to open up to Internet traffic (for example 6000-6200).  
Input Protocol   
Select the protocol used by the Internet traffic coming back into the router through the 
opened port range (for example Both).  
Schedule  
Select a schedule for when this rule is in effect. If you do not see the schedule you need 
in the list of schedules, go to the To o l s  → Schedules screen and create a new schedule.   
With the above example application rule enabled, the router will open up a range of ports from 
6000-6200 for incoming traffic from the Internet, whenever any computer on the internal 
network opens up an application that sends data to the Internet using a port in the range of 
6500-6700.

Advanced_Gaming 
Multiple connections are required by some applications, such as internet games, video conferencing, 
Internet telephony, and others. These applications have difficulties working through NAT (Network 
Address Translation). This section is used to open multiple ports or a range of ports in your router and 
redirect data through those ports to a single PC on your network. You can enter ports in various 
formats:  
Range (50-100) 
Individual (80, 68, 888) 
Mixed (1020-5000, 689)   
 
 
Example:  
Suppose you are hosting an online game server that is running on a PC with a private IP 
Address of 192.168.2.50. This game requires that you open multiple ports (6159-6180, 99) on 
the router so Internet users can connect.    
						

							30 
Port Forwarding Fields   
Name  
Give the rule a name that is meaningful to you, for example Game Server. You can also select 
from a list of popular games, and many of the remaining configuration values will be filled in 
accordingly. However, you should check whether the port values have changed since this list 
was created, and you must fill in the IP address field.   
IP Address   
Enter the local network IP address of the system hosting the server, for example 192.168.2.50.  
TCP Ports To Open   
Enter the TCP ports to open (for example 6159-6180, 99).  
UDP Ports To Open   
Enter the UDP ports to open (for example 6159-6180, 99).  
Inbound Filter   
Select a filter that controls access as needed for this rule. If you do not see the filter you need 
in the list of filters, go to the Advanced → Inbound Filter screen and create a new filter.   
Schedule  
Select a schedule for the times when this rule is in effect. If you do not see the schedule you 
need in the list of schedules, go to the Tools → Schedules screen and create a new schedule.   
With the above example values filled in and this Gaming Rule enabled, all TCP and UDP traffic 
on ports 6159 through 6180 and port 99 is passed through the router and redirected to the 
Internal Private IP Address of your Game Server at 192.168.2.50.   
Edit/Add Game Rule

Advanced_StreamEngine 
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.    
						

							32 
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 ISPs 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 reported 
slightly lower than before on such connections, but gives much better results.   
Detected xDSL or Frame Relay Network   
When Connection Type is set to Auto-detect, the automatically detected connection 
type is displayed here.   
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  
						

							33 
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.

Advanced_Routing 
 
 
Add/Edit Route   
Adds a new route to the IP routing table or edits an existing route.   
Enable: Specifies whether the entry will be enabled or disabled.   
Destination IP: The IP address of packets that will take this route.   
Netmask: One bits in the mask specify which bits of the IP address must match.   
Gateway: Specifies the next hop to be taken if this route is used. A gateway of 0.0.0.0 implies 
there is no next hop, and the IP address matched is directly connected to the router on the 
interface specified: LAN or WAN. 
Interface: Specifies the interface -- LAN or WAN -- that the IP packet must use to transit out of 
the router, when this route is used.   
Metric: The route metric is a value from 1 to 16 that indicates the cost of using this route. A 
value of 1 is the lowest cost, and 15 is the highest cost. A value of 16 indicates that the route is 
not reachable from this router. When trying to reach a particular destination, computers on your 
network will select the best route, ignoring unreachable routes.

Advanced_Access Control 
The Access Control section allows you to control access in and out of devices on your network. Use 
this feature as Parental Controls to only grant access to approved sites, limit web access based on 
time or dates, and/or block access from applications such as peer-to-peer utilities or games. 
 
Enable  
By default, the Access Control feature is disabled. If you need Access Control, check this 
option.  
 
 When Access Control is disabled, every device on the LAN has unrestricted access 
to the Internet. However, if you enable Access Control, Internet access is restricted 
for those devices that have an Access Control Policy configured for them. All other 
devices have unrestricted access to the Internet.   
 
Policy Wizard   
The Policy Wizard guides you through the steps of defining each access control policy. A 
policy is the Who, What, When, and How of access control -- whose computer will be 
affected by the control, what internet addresses are controlled, when will the control be in 
effect, and how is the control implemented. You can define multiple policies. The Policy Wizard 
starts when you click the button below and also when you edit an existing policy.   
Add Policy   
Click this button to start creating a new access control policy.
