Port Forwarding Guide
For automatic port forwarding try Simple Port Forwarding

Step 1.

Some routers & modems work best with port forwarding if you have a static local IP.
Manually set your network interface card ( NIC ) to use a static ip address.
You can also download my FREE Simple Static IP tool to set it for you.

Step 2.

Open your favorite web browser and input your routers ip address in the address bar.
Please note that you must have the http:// in order to connect to your router/modem properly.
