Again without knowing what model you have all I can do is guess. I can also guess that you did not read anything that was in the link I gave you because it tells you exactly how to do it step by step it even has a nice little picture.
This is what it says on the first link in the list I linked you to about port forwarding and a netgear router titled How is Port Forwarding Configured?. The following is a direct link to this page:
http://kbserver.netgear.com/inquira...es/n101145.asp&answer_id=43762500#__highlight
Here is a copy of exactly what it says on that page. Again this is not model specific as I have no idea what model you have, you or the person who setup it should know this info. If this is not correct you will need to look it up for your specific model.
To Create a New Inbound or Outbound Rule
1. Submit the router's address in an Internet browser. (The default is 192.168.0.1).
2. Enter the router's username and password.
3. From the main menu, click Security > Rules.
4. Click Add for inbound or outbound traffic, as appropriate to the application you are planning to run.
5. Select the Service. The services the router knows about are listed in the drop down. If the service you want is not listed, add it as described in the next section.
6. Select the Action, for example ALLOW always.
7. For Send to LAN Server, enter the IP address of the local server. Note that this is also the IP address the computers on your LAN will access.
8. For WAN User choose Any, or limit access to particular IP addresses.
9. For Log selection it is reasonable to turn logs on, especially at the beginning when you are unsure of the result of the changes you are making. Later, you may want to set logs to "Never" for performance reasons.
10. Click Apply.
The router username is always admin
The default password is password or 1234
If your router does not have the default password still on it then ask your dad what it is because he probably changed it.
