Is this to help you set up the port forwarding?
If so, this is how it works:
Step 1. Do the IPCONFIG thingy to get the IP address your router's giving you. It'll probably be 192.168.XXX.XXX Make note of the first 3 sets of numbers (the 192.168.XXX.___ part).
Step 2. Make up a new number for the last part. Most routers make the last number > 100, so something like 10 or 20 would work. If the last number is <100, then make up a number like 200.
Step 3. Mix the 2 numbers together. It should be 192.168.XXX.
your number. You just made yourself a new static IP address...
Step 4. Odds are, you're also going to need to find your
DNS servers. IIRC, you can find the ones your ISP wants you to use in your router somewhere. Find them, and write the first (only) 2 down.
Step 5. Go to the Internet Connections part of the control panel. On the screen where you add your IP address, give it your made up Static IP, then the 2 DNS servers you wrote down.
Step 6. Go back into the router (if you did everything right so far, you should have no problem getting there), and set up the port forwarding...
