DLinkDDNS and TS3

[WPanayides]

Hey guys im wondering if anyone can help me im trying to setup a ts3 server which is installed and i can connect via local ip. but im trying to tunnel it through a DLink 2750u router using DlinkDDNS but cant see it i've tried everything i have manually set the server machine to the DMZ that didnt work i have tried Port forwarding ports 9788, 10011, 30011, this machine i also want to setup a XAMPP server to host a gaming website.. 

 

Server Machine is a P4 3.2Ghz, 1gb ram on a intel server board. running Windows Vista 32bit

Client Machine is a i7 920 4.0Ghz 12Gb Ram on a flaming blade gti running Windows 8.1 64bit

 

both are connected via the DLink 2750u router and my android phone

 

My android phone can connect to the ts3 server when running on the Wifi but fails when running on its own 3g connection [My external test device]

Have you set a static IP address. It could be changing and causing the issues
