How to set up port forwarding on the Hitron CGNv4

• Log into the Hitron CGNv4 GUI through 192.168.0.1 and navigate to the ‘Basic’ section in the header, highlighted in red.
• Click on ‘Port Forwarding’ in the left hand column, highlighted in purple.
• Click the ‘Enabled’ button and then click the ‘Add’ button to insert your port forwarding rule.

You can obtain the information needed for the port forwarding rule at the portfroward.com website. Although the instructions are not for the exact same model as your CGNv4 router (they're for the CGNv3), it has the same functionality and a very similar layout and setup.
