The first step is to setup your Buffalo WZR-RS-G54 Router using the Setup Wizard or you can configure the router using the ADVANCED button when you first log into the router. Once you have the router set up and running (you can access the Internet when you are using the router), you can continue below to setup the TZO Dynamic DNS services. The TZO Dynamic DNS can be very helpful when using the TightVNC client and server software included with the router, or you can use it to run your own web server, email, FTP, remote desktop, VPN, photo server and much more.


Step 1) Below is a screenshot of the TZO.COM signup page where you can signup with a free 30 day trial of TZO DDNS for your Buffalo router. To get your free trial domain, you should signup at http://Buffalo.tzo.com - If you already have a TZO.COM account, you can skip directly to step 2 below

Once you reach the Buffalo signup page as shown below, you need to enter in your choice for your domain name, and then your email address, and then click on the Create My Free Trial Domain button. Once you do this, TZO will send you an email with your trial key. Once you get the email with your TZO trial information, you should write down your TZO DOMAIN name, and your TZO Key before proceeding to step 2.

The Signup page Buffalo.tzo.com allows you to signup for a free trial of TZO with custom domains

Step 2) Now that you have signed up (free trial or paid account) with TZO DDNS, you need to enable the TZO DDNS in the router and then enter in your TZO Key, Domain Name and Email address into the Buffalo router.

To do this, Log into the Buffalo router as described in the Buffalo manual that came with the router. Once you do this, click the ADVANCED button on the first login screen. (This screen is not shown)

Once you click the advanced button, you will see the main screen of the router similar to the screen shown below. You should now click WAN SETTINGS and you will see a WAN SETTINGS page. To get to the Dynamic DNS section you must then click the Dynamic DNS button (Shown highlighted in the screenshot below)




The main WAN SETTINGS page of the Buffalo WZR-RS-G54 router. You need to select the Dynamic DNS section in order to configure the TZO Dynamic DNS service in the router. (Click to Enlarge)

Step 3) Your next step is setup the Dynamic DNS as shown as shown in the screenshot above. You will now see the TZO Dynamic DNS service option, as well as fields to enter in your TZO Key, Email and Domain name. Select TZO from the Drop down list and click the ENABLE radio button. Then enter in your information from your TZO account in the proper fields as shown.

Note these fields should have the information as follows:

HOST NAME = Your domain name
DOMAIN NAME = tzo.com
USERNAME = Email Address
PASSWORD = TZO Key

Once you do these above steps and your screen looks similar to the screenshot above, click the APPLY button at the bottom left of the screen. Doing this will force a DDNS update to the TZO DDNS servers.

The Network Settings - Address Translation shows the Enter NAT TABLE button (Click to Enlarge)

 
Step 4) Now that you have setup the TZO DDNS in the router, your domain name should be pointed to the current IP address of the router. You can now setup the router's NAT firewall to forward the proper ports to an internal server such as a Web server, email server, FTP, etc.

In this example, we show how to setup a web server to work with the Buffalo router. In order to forward ports to a server connected to the router, you need to select the NETWORK SETTINGS section and then click on the ADDRESS TRANSLATION button as shown in the screenshot above.

In order to forward ports, you must add the IP Address,WAN and LAN Protocol and Ports to the NAT table as shown in the screenshot above. (Click to Enlarge)

Step 5) In this example as shown above, we added a web server to the SERVERS group that we defined. This change to the NAT TABLE allows us to forward the WEB port (port 80) to that specific host (192.168.12.3). After entering this information in, select HTTP from the dropdown list of services, and then select the ADD button to add HTTP port forwarding to the application server called LAPTOP as shown below.

Now that you have added the IP Address, Protocol and Port forwarding information to the NAT table, you should click the ADD TO NAT TABLE to save these settings. Once the screen refreshes, you must hit the APPLY button to apply the changed settings to the NAT Table. If you do not do this, the settings will not be saved.

That's it! To add other application servers and services, simply repeat Step 4 and 5 for each additional server and service you wish to run. If you have more questions on the Buffalo series of routers and other products, please see the Buffalo Technology website

If your ISP blocks access to port 80 inbound, you can use the TZO HTTP Relay services to get around the blocked ports. For more information on the TZO HTTP relay and other services offered by TZO.COM, please see the website at http://www.tzo.com
