How does the Port Relay work?
Port relay works by directing your web traffic to our web server, once the person browsing your web site hits our server we grab the web address they typed into their web browser and cross reference it with our database and pull up the redirect address you are pointing your web traffic to, and redirect the browser to your server address on the port you specified within an invisible frame.


Instructions for Setting Up Basic Port Relay:
If you are relaying a static IP address (an address that does not change), the setup for port relay is fairly straightforward: Log on to your account using the Dynamic DNS Application. After you've logged in, click the Add button which will open up the add record screen shown below. Choose the domain you wish to add port relay to, select the Port Relay record type, and fill in the "Pointing To" and "Port" fields.

Pointing to: The "Pointing To" address is the address people will be redirected to when they enter your web address (for example "http://www.georgeluis.com") into their web browser. You may insert a fixed address, a web site or let the application automatically enter an address by checking the "Automatic IP Resolution" box. If you wish to redirect people to an alternate port such as port 8080, your local web server must be configured to receive HTTP requests on that port. (Here's a link to "How to change the port IIS uses") You also have the ability to relay people going to your domain such as http://www.georgeluis.com to another web site by typing in the address you want them redirected to such as http://members.aol.com/mysite/. You cannot however point them directly to a web page (I.E.: http://members.aol.com/mysite/default.asp). The same rule applies if you're pointing them to an IP address (I.E.: http://68.15.187.28:8080/default.asp).

Note: A root domain is a domain that has no prefix before it: "yourdomain.com" is a root domain, "www.yourdomain.com" is a sub domain. If someone enters http://yourdomain.com into their browser, they are going to the root domain, if they enter http://www.yourdomain.com they are going to the "www" sub domain of yourdomain.com. Most web surfers are unaware that there is a separate record for each of these locations. Because some web surfers use the root domain address and some use the sub-domain address, you may want to set create relayed records for your root domain (yourdomain.com) and your sub domain (www.yourdomain.com) and point to the same location.

Instructions for Setting Up Dynamic Port Relay:
If the IP address that you are setting up a port relay on is a Dynamic IP address (one that changes at an interval defined by your Internet Service Provider), the setup requires a different approach from the one used for setting up the Basic Port Relay: First log in to your account using the Dynamic DNS Application. After you've logged in, click the Add button which will open up the add record screen shown below. Choose the domain you wish to add port relay to, select the A record type, and name this record (relay is a good name, since it's easy to remember). Select the "Automatic IP Resolution" checkbox. Your Current IP address will be entered in the Pointing To field automatically. Click the Update/Add button to complete this step and return to the main status window.

Adding the Port Relay Record(s): Next, click the Add button again to open up the add record screen shown below. Choose the domain you wish to add port relay to and select the Port Relay record type. Leave the Name field blank. In the Pointing To field, add relay.yourdomain.com, replacing "yourdomain.com" with your domain name. Enter a port number to relay to in the Port field (This can be any port, many people like to use 8080 as it is easy to remember.). Make sure that the Automatic IP Resolution checkbox is NOT selected. Click the Update/Add button to complete this step and return to the main status window.

Optional: Add a record pointing to a subdomain. Following the same basic steps as before, you can add a subdomain to the port relay such as "www". This allows a person surfing to your website to enter http://yourdomain.com OR http://www.yourdomain.com and still reach your relayed web site. An example is shown below.

Known issues with Port Relay:

HTTP Relay does not work with Mail, FTP, Telnet or any other type of records. HTTP Relay will only work with web traffic. Most ISP's only block web traffic on port 80. To set up other records such as Mail, FTP, Telnet you must use the Add/Edit Domain Records menu selection. Please see setting up DNS records for more information.
