    I am intrested in making a program that can be used to search a ip for open ports. The only problem is i dont know how to go about having it actually use the internet to check the ports... Any suggestions and comments would be greatly appreciated.

    You need to have an external server, outside of any firewalls, and have that server send a request to a port on the client machine. If the program on the client machine receives the request from the server, then the port is open, otherwise not.
