That's better. I don't know whether your device supports UPnP or not. Using your browser, type 192.168.1.1 into the address bar. This should enable you to telnet into your device. You should see a box prompting you for your username and password. Enter your username and password now. By default both the username and password are root. (try admin if your admin account name doesn't work.) Click the Ok button to log in to your router. Check the different sections & see if you can find a UPnP (Universal Plug & Play) option. If not, then you will need to forward a port.

One of the most important steps for forwarding a port is the 1st one which is setting up a static ip. So follow the instructions on the following page carefully: Port Forwarding for the CTC Union ATU-R130. Some devices you need to reboot the device to save the information properly. I'm not sure about your brand.
