Custom DNS troubleshooting

Hello,

I have purchased a domain and also the Custom DNS from Dyndns. As for now, I still cannot get connected to my server. I have followed the troubleshooting guide here: .../support/kb/why_cant_i_connect_to_my_server.html#testip and all looks fine until "Step Three: Test the Port" (inclusive)

...I have also done a DNS lookup from (...dnscog.com/dig/) and the results were as below:

When registering the domain, I have set the followings:

Primary Nameserver: http://ns1.mydyndns.org
Secondary Nameserver: http://ns2.mydyndns.org

Did I miss out something?

Thank you in advance for the suggestions.
