hi vb , im sorry if i posted in the wrong section
right here is wats wrong
i want web server accessible to the web but i need to configure my router i dont know how to do this
i did these steps

5.Once installation of IIS is done, the web server is running on the Vista system without any further configuration. You can check the functionality of the new web server by pointing to http://localhost/ from any web browser or surfing to the computer name within local area network (LAN), where you should see a IIS7 default page. To make the web server accessible from Internet, you will have to configure your router and DNS services.

thats what i need to do configure the router and DNS services how do i do this step by step please thanks
