(Demilitarized Zone) Applications and Gaming > DMZ The DMZ feature allows one network computer to be exposed to the Internet for use of a special-purpose service such as Internet gaming or videoconferencing . DMZ hosting forwards all the ports at the same time to one computer . The Port Range Forwarding feature is more secure because it only opens the ports you want to have opened, while DMZ hosting opens all the ports of one computer, exposing the computer to the Internet . Applications and Gaming > DMZ DMZ Any computer whose port is being forwarded should have its DHCP client function disabled and have a new static IP address assigned to it because its IP address may change when using the DHCP function . Enabled/Disabled To disable DMZ hosting, select Disabled . To expose one computer, select Enabled . Then configure the following settings:

Source IP Address If you want any IP address to be the source, select Any IP Address . If you want to specify an IP address or range of IP addresses as the designated source, select and complete the IP address range fields .

Follow these instructions until your computer can connect to the Internet:

Verify that the power adapter is connected to the Router and to a power outlet . If connected to a power strip, make sure the power strip is turned on . Make sure that the Power LED, Internet LED, and Wireless LED are on . If you have any wired computers connected to the Router, make sure the appropriate port LED is lit . NOTE: The Power LED flashes after the power adapter is plugged in to the Router . If the light remains flashing for more than 30 seconds, it may indicate the Router is not working properly . For assistance, use a computer or device with Internet access to refer to our Linksys E1550 support section on the web at www.linksys.com/support Make sure that your DSL or cable modem is connected to your Routers Internet port using an Ethernet cable . Reset all of the devices on your network:

1 . Turn off all of your network computers and devices, and then unplug the power adapter from your Router . 2 . Unplug your modems power cord (and coaxial cable if you have a cable modem), and wait two minutes . 3 . Reconnect your modems power cord (and coaxial cable) and wait two more minutes . 4 . Reconnect the power adapter to the Router, and then power on all of your network computers and devices . The modem does not have an Ethernet port. The modem is a dial-up modem for traditional dial-up service . To use the Router, you need a cable/DSL modem and high-speed Internet connection . You cannot use the DSL service to connect manually to the Internet. After you have installed the Router, it will automatically connect to your Internet Service Provider (ISP), so you no longer need to connect manually . The DSL telephone line does not fit into the Routers Internet port. The Router does not replace your modem . You still need your DSL modem in order to use the Router . Connect the telephone line to the DSL modem, and then insert the setup CD into your computer . Click Set up your Linksys Router and follow the on-screen instructions . When you double-click the web browser, you are prompted for a username and password. If you want to get rid of the prompt, follow these instructions. Launch the web browser and perform the following steps

(these steps are specific to Internet Explorer but are similar for other browsers):

1 . Select Tools > Internet Options . 2 . Click the Connections tab . 3 . Select Never dial a connection . 4 . Click OK . The Router does not have a coaxial port for the cable connection. The Router does not replace your modem . You still need your cable modem in order to use the Router .
