How to configure the 'True IP DMZ' with a PPPoE WAN connection? [EN]

In some cities of China, broadband services require strict Web Login/ Authentication before any Internet access can be through. It is expected that a True-IP DMZ host can carry out the login/authentication smoothly.

Here, we take Vigor2920 as an example.

I. Setup True IP DMZ host

The True IP DMZ host must get its IP via DHCP client. The Vigor router will check the source MAC address of the DHCP requests to identify the True IP DMZ. Here we take Windows XP for example. Select the TCP/IP protocol as shown below and click on Properties and then check that Obtain IP address automatically & Obtain DNS server address automatically are both selected.

Network-Configuration

Open the Command Prompt from Start > All Programs > Accessories and type the command ipconfig/all. Record the Physical Address, 00-E0-4C-51-91-AA.

Note: You will find that at present this PC has obtained a private IP address from Vigor2920 DHCP Server.

II. Setup WAN connection in Vigor2920

1. Access into the WUI of Vigor2920.
2. Open WAN>> Internet Access and choose PPPoE mode.

WAN >> Internet-Access

3. Click Details Page to open the following page.

WAN >> Internet-Access

4. Click Enable. Type the username and password.
5. Press OK and wait for the router to reboot.

III. Setup True IP DMZ in Vigor2920

1. Access into the WUI of Vigor2920.
2. Open NAT>>DMZ Host.

NAT >> DMZ-Host-Setup

3. Select Active True IP from the pull-down menu.
4. Type the MAC address (e.g., 00-E0-4C-51-91-AA) of the DMZ host.
5. Press OK and wait for the router to reboot.

IV. Get the public IP

After the router has rebooted, go to Online Status page and confirm the router has connected to the ISP. Although the router has obtained a public IP address, you can't access the Internet at present for the ISP requires strict Web login/Authentication.

Online-Status

Open the Command Prompt from Start > All Programs > Accessories and type the command ipconfig/release, then ipconfig/renew. You will find that Vigor2920 assigns the WAN IP and associates default gateway to the True IP DMZ host. You can run ping to confirm if this PC can connect to the Internet.
