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.
