about Aztech DSL605E

Good day, ragezonerz out there! I have a noob question for you: Is it possible to make it direct server using Aztech DSL605E? I tried so many time but still it fails. Meaning, can't connect to game outside my home. It only works for lan game only after portwarding. At here, the internet connection is Globelines broadband and I used tp link 8 port switch. I'm so tired for trying to direct the server. I don't want to use hamachi anymore, I want to work it as direct server. Can someone tell me how to do it? If you can't, don't reply....

Thank you and more powers to you, ragezoners....^_^v

most important thing is, do you have public IP address?
then on aztech usualy you can forward all your port to local server, tipicaly on every adsl router modem, port forwarding or virtual server...but its same
