Connection doc and dynamic ip

I am using dynip.com to resolve a dynamic ip address connection document.

When I put in nowoffers.dynip.com as the “optional network address” the console trace shows it finding 24.24.92.26 which is the appropriate wan router dyamic address. At this point it displays a “server not responding” message. The firewall is open. My router is port forwarded to http/smtp/pop3 ports.

Any ideas?
