That is easy, they provide you with a way to redirect. You setup your website on some other port like say 8888 and you setup their redirect.

“How can I redirect to a different port?

You can redirect by entering the port in the redirect URL box as you would if you were entering the address in your browser. To redirect hophost.webhop.net to yourport on your host yours.dyndns.org, you would enter http://yours.dyndns.org:yourport/ as the redirect URL for hophost.webhop.net.”

What you do is sign up for their service, and then install their updater tool on the same computer or another computer on your internal network. How this tool works is it checks on an interval your remote IP and updates the Dynamic DNS service. Pretty cool. Now you can remember a human readable domain name instead of your IP address! [...]
