ehcp and dyndns

I registered my domain name with dyndns.com and when I put my address in I get the ehcp log in page. did i do something wrong or is this normal?

in ehcp, add/setup your domain,
if you already did, options->sync domains,
if still not working,
make sure /etc/apache/apache.conf contains ehcp related lines at bottom.

Now when I put in my address I get the EHCP default website page that has the link to click to go to the log in page for ehcp. so now what?

what lines should I be looking for?

so when you put in your dyndns name you get the default webpage?

have you added the dyndns name to your control panel as a domain?

ie. blank.dyndns.com
