LAN not routing back to DDNS address

Working with my Gold Plus and seem to having an issues I'm just not getting right in my head.  I have a DDNS set up.  I use it for Web and other interface.  When I'm connecting from an external location, all the routing works flawlessly.  Every service I set up is available.

But when trying to access the same DDNS location/any port it seems that internal routing isn't working. BUT if I initiate a PING command, the DDNS IP (WAN IP) address is resolved properly.

What can I do to fix this/get it to work right?
