Online Gaming

Read this chapter if you are going to use your Cable Modem/Router for online gaming.

Some online games require you to make changes to your firewall. This chapter explains

the different ways you can modify the firewall to allow your online gaming system access.

Gaming

If you are using your router for gaming, you may need to make changes to the router’s

firewall setting for the game to work. This is done by setting up a

DMZ

or using

Port

Triggering

so that the Cable Modem/Router’s firewall won’t block the other players

from your system during your gaming. The main difference between the methods is the

amount of access someone has to your system.

A DMZ allows access on all ports of the computer. Because of this, DMZ's are less

secure and should be used with caution with your computer. However DMZ’s work well

with gaming stations since security is not as much of an issue for gaming stations as it is

for computers.

Port triggering works by sensing when data is sent out on a predetermined outgoing port

and then automatically opening up the corresponding incoming port(s). It will

automatically forward the traffic on the incoming port to the computer that accessed the

outgoing port. If your game uses one port to send outgoing data and a different port (or

ports) for incoming data, you may want to use port triggering. You do not need to know

the IP address of your gaming station to set up port triggering. You will need to know

which ports your game requires you to open. This information is usually available with

your gaming software or you should be able to find it by searching for it on the web.

DMZ Host

The DMZ (De-militarized Zone) Host page allows you to configure a network device (e.g.

a PC or gaming system) to be visible directly to the Internet. This may be used if a game

doesn’t work with port triggers or if you are using a gaming system, where security is less

of a concern.

To set up a DMZ for your gaming system, you should first assign your gaming system a

static IP address.

Normally the Cable Modem/Router handles assigning IP addresses

to the different devices on your network using DHCP.

However DHCP does not

guarantee that your device will always get assigned the same IP address. The DMZ

needs to know the IP address of your gaming system to work, if the IP address changes

the DMZ will not work. Because your IP address could change over time you need to

assign a static IP on your gaming system. To setup a static IP address on your gaming

system, please refer to your gaming system’s documentation. If you no longer have the

documentation that came with your gaming system it usually can be found online.

When assigning a static IP address to your gaming system you should select an address

that is outside the IP addresses assigned by the Cable Modem/Router’s DHCP server.

By default the DHCP Server assigns addresses from 192.168.0.10 to 192.168.0.255.

We recommend using 192.168.0.5 as the static IP address for your gaming system.

To setup a

DMZ

for your gaming system:

1

Follow the instructions for your gaming system to assign a static IP address. We

recommend using 192.168.0.5.

2

Next access the Cable Modem/Routers configuration menu by launching a Web

browser on a computer that is directly connected to one of the router’s LAN ports.

3

In the browser address bar, type

and press the

Enter

key.

4

In the Login screen, enter:

default username:

admin

default password:

admin

Both the username and password are case sensitive. The default username and

password are printed on the label of your unit. When the cable modem is standing

vertically this label is located on the side of your modem.

5

Click the Login button to access the Cable Modem/Router. The

Status

page

appears.

6

Click

Advanced

in the menu bar.

7

Then click the

DMZ Host

submenu. The

DMZ Host

page appears:

8

Enter the last byte of the LAN IP address of the static IP address you assigned to

your gaming system. For example if you assigned 192.168.0.5 enter

5

.

9

Click

Apply

.

Your gaming system should now work with all your online games.

Port Triggers

Port Triggering works by sensing when your game sends data out through a specific

port. The outgoing data signals the router to allow the incoming game traffic to be passed

through the firewall on the correct port.

Since the ports are only open when you are

gaming, port triggering is a very secure method for online gaming.

To set up port triggering you need to know what ports your game is using and whether

they use TCP, UDP or both on those ports. Typically this should be included with your

gaming software. If it is not included, try entering the name of your gaming software

followed by “ports used”.

Some games use the same ports for both incoming and outgoing traffic, while other

games use different ports for incoming and outgoing traffic.

Below is an example of setting up the popular game, World of Warcraft for port triggering.

Looking online, we find that World of Warcraft uses the following ports: 1119-1120, 3724,

4000, 6112-6114, and 6881-6999.

We can also find out that these ports are all TCP.
