I have some questions about port forwarding on my D-Link Router GLB-802C.

For example:

* My local machine's IP is `117.1.1.81`
* My router's IP is `117.1.1.1`
* My Public (Web) IP is `117.16.1.1`

My questions are:

1. What will be my Global Address 'To'?
2. What will be my Global Address 'From'?
3. In Destination Port "From" and "To" what do I select in the drop down list and port no for forwarding HTTP traffic (for my website)?
4. In Local Port, what do I select in drop down list and port no?
