Globe Wimax doesn't allow port forwarding

This is Teamviewer 6 on a Debian Linux

Have you been a Globe Wimax subscriber and realized, why can't I forward a port? You need to forward your port if you have an IP Camera in your network and wish to view it from the internet, browse and transfer files from your NAS (Networked Attached Storage), or Host your own website from your computer, or you want to host a game server for your friends to logon to.
