@eobox91103 You shouldn't need software to do port forwarding. It varies widely from one router to another. Simply put, you login to your router's admin console webpage and go through your NAT settings. As a general rule, I also recommend binding your computer's MAC address to a dedicated IP address in your router's DHCP settings as well so that you don't have to adjust your port forwarding every so often as the IP address changes.
The most comprehensive method I know of is portforward.com
