Open a web browser like internet explorer or Netscape. Enter the ip address of your router in the address bar of your browser. In the picture above the address bar has
Google in it. Just replace all of that with the ip address of your router. By default the ip address should be set to 192.168.1.1.
You should see a box prompting you for your username and password. Enter your username and password now. By default both the username and password are
admin. Click the
Ok button to log in to your router.
Click the
Advanced Setup link near the left of the page.
You should now see a new menu. In this new menu, click
NAT.
Click the
Add button near the center of the page.
Put a dot into the
Custom Server radio button. Enter the name of the program into the
Custom Server box. It doesn't really matter what you put into this box, but something that will remind you why these ports are being forwarded would be a good idea. Enter the ip address to forward these ports to into the
Server IP Address box. If you are forwarding ports so you can run a program on your computer, you should enter your computer's ip address into that box. If you are forwarding a single port, enter that port number into the
External Port Start,
External Port End,
Internal Port Start and
Internal Port End boxes. If you are forwarding a range of ports, enter the lowest number of the range into the
External Port Start and
Internal Port Start boxes. Then enter the highest number of the range into the
External Port End and
Internal Port End boxes. Use the
Protocol drop down box to select the protocol type of the ports you are forwarding. When you're finished, click
Save/Apply near the bottom of the screen to save your changes.
