DNS problems with local hosts especially with Iphone/Ipad

I have some problems communicating with different devices each other in my local network. I suggest some DNS problems or incorrect DNS settings

First of all, a short overview of my devices:

Internet works fine on all devices! All clients have set the DNS to the IP of my router. The router also has the settings for port forwarding from port 80 to port 80 of my Webserver as well for port 8080. To access to my Webserver outside my local networks also works fine, but....

Problem 1) Resolving public dyndns-address

When I ping my public address mysubdomain.dyndns-home.com inside my local network, the IP will be resolved correctly without any timeout problems on all devices, but when I use my public address in a browser (Chrome, Firefox, IE) there is a timeout error message or server down message. This is the same behavior on all devices. So why can I not use my public address in my local network? To change that, what do I have to change?

Problem 2) Resolving local devices on Iphone/Ipad

Because I can not use my public address in my local network I want to communicate by my local device names. So all my devices are registered by their mac-address in the router. When I log into my router I can see all devices and their IP-addresses which are currently running. So if the router is the DNS for my clients, the router should resolve the local device names. That works so far for the Computers running Windows or Linux. But on my Iphone or Ipad the names will not be resolved. I also tried to refresh the lease or to forget the network and reconnect again, but still I can not communicate with my Iphone/Ipad and my other devices. So what can I do to resolve the names on my Iphone/Ipad?

Thanks for your help

1) Because you are in your local network you have to use private ip (you can see private ip using ipconfig on windows or ifconfig command line on linux). The public ip is for all others computers on the network. If you want test that the server works correctly you can use a proxy (like www.anonymouse.org)
