Dual Router Configuration:

Actiontec GT701 DSL Modem and LinkSys WRT54G Wireless Router/Switch

This document describes the steps that I took to make my HP EX485 Windows Home Server accessible

from the Internet. I have a dual router configuration, with a Qwest provided Actiontec GT701 DSL

Modem/Router connecting me to the Internet and a LinkSys WRT54G wireless router/switch connected

to the GT701 (via the WRT54G's WAN port) providing local area networking to my wired and wireless

PCs and printers. The EX485 server is plugged into a switch port on the WRT54G. To make the

EX485 accessible from the Internet you have 2 choices. You can either place the WRT54G in the

GT701's DMZ or you can can set the GT701 and WRT54G into a “dual port forwarding” configuration.

In this configuration the GT701 forwards the necessary ports to the WRT54G and the WRT54G

forwards them to the EX485. I have used both methods and prefer the “dual port forwarding option

which I describe in this document. It is easier to set up and is (I think) more secure than placing your

WRT54G into the GT701's DMZ.

NOTE: These instructions assume that your GT701's IP address is 192.168.0.1 and your WRT54G's IP

Address is 192.168.1.1. If yours are different, use yours instead. Also, in my case I set a static IP

address of 192.168.1.200 for my EX485 (You want to use a static IP for your EX485 so that it's IP

address never changes and you can reliably do port forwarding to it). You can use an address other

than “200” if you prefer. If you do, just remember to substitute that number for “200” in the

instructions below. The instructions also assume that your Qwest assigned primary DNS address is

205.171.3.65 and your secondary DNS address is 205.171.2.65. You should double check that before

implementing these instructions. If your addresses are different, use them instead of the ones in these

instructions. You can get the DNS addresses by contacting Qwest support. You can also get them by

logging into your Actiontec GT701. Your DNS addresses will be displayed at the bottom of the main

Status page.

DISCLAIMER: These instructions worked for me with the equipment stated. You should be able to

make these steps work with other modems and routers as long as they support port forwarding. The

concepts should be the same although the exact steps and screens will vary. However, even if you have

this exact same equipment, do not go into this lightly. There is the possibility that you will make

changes that will make your modem or router cease to work properly, in which case you would have to

reset them back to factory defaults and start over again. Be sure that you have a backup plan before

proceeding! That backup plan should include, at a bare minimum, logging into your GT701 and

WRT54G and recording all non-factory settings that you may have made to these devices. It is

particularly important that you have your Qwest DSL “PPP Username” and “PPP Password”. You will

need these in order to get back onto the Internet if you have to do a hard reset on the GT701. If you

don't have this username and password call Qwest right now and get it. I have included instructions for

resetting both the GT701 and WRT54G back to factory defaults at the end of this document.

One additional note: For reasons that I can't explain, sometimes the GT701 and WRT54G may need to

be power cycled between steps. If you have made changes to one or the other and things aren't

working, before you panic, try powering off both devices. Then power the GT701 on first. Wait until

you have green power, DSL, and Internet lights and then power on the WRT54G. Often this makes

things happy again. If it doesn't, and all else fails, you will have to reset both devices back to factory

defaults (described at the end of this document) and start over again.

Ok, let's get started. It is important that you perform these instructions in the order shown below.

Dual Router Configuration: Actiontec GT701 DSL Modem and LinkSys WRT54G Wireless Router/Switch This document describes the steps that I took to make my HP EX485 Windows Home Server accessible from the Internet. I have a dual router configuration, with a Qwest provided Actiontec GT701 DSL Modem/Router connecting me to the Internet and a LinkSys WRT54G wireless router/switch connected to the GT701 (via the WRT54G's WAN port) providing local area networking to my wired and wireless PCs and printers.

Give The EX485 Windows Home Server a Static IP Address: • • • • • • • • • • • • • From a PC on your network, do a “Remote Desktop” login to your EX485. To do this in Windows Vista click “Start”, “Accessories”, and “Remote Desktop Connection”. When prompted for “Computer”, enter the name of your computer (or its IP Address) and click “Connect”. At the Windows Home Server login screen, enter “Administrator” for the Username and then enter the Administrator password that you assigned your EX485 during setup.

Follow the screen instructions to set a username and password. Click the “Status” tab to get back to the main status screen. On the left side of the screen click “Active User List”. You should see 1 active user on the GT701. That user is your WRT54G. Make note of the IP address. In my case it is 192.168.0.3.

Start IE and browse to 192.168.0.1 to open the GT701 configuration utility. NOTE: If things are really messed up you may not be able to connect to the GT701. If you try connecting and it fails you will need to unplug your PC from the switch port on the WRT54G and plug it directly into the back of the GT701.
