If you don't know what Port Forwarding is yet, you might want to start by reading our What is Port Forwarding guide.
You might also be interested in our huge collection of Router Screenshots where you can see every page of every router that we know of.
Now we need to know your routers IP address. You can find it a variety of ways.
It's ok if you don't know your Actiontec GT704-WG router's internal IP address. You can find it by doing one of the following:
Open a web browser like Internet Explorer or Firefox. Enter the internal IP address of your router in the address bar of your browser.
In the picture above the address bar has http://www.google.com in it. Just replace all of that with the internal IP address of your Actiontec GT704-WG router. By default the IP address should be set to 192.168.0.1.
If you are having trouble with this guide, then perhaps PFConfig may be your solution. PFConfig is a software tool that will automatically forward ports for your Actiontec GT704-WG router to save you time and hassle.
