forwarding to be fully enabled.
Note
If your host systems/applications do not have communications issues with the
Internet, forwarding is not needed.
You need two major items of information to setup forwarding:
 The IP address of each local host system (for example, Xbox) for which you need to
setup a port forwarding rule. See the discussion below for how to obtain IP addresses.
 The port numbers that a local host's application listens to for incoming requests/data
(for example, a game or other service). These port numbers should be available in the
documentation associated with the application. You may also refer to
http://portforward.com
The following tasks are recommended as best practices for setting up forwarding rules:

recommend that you assign a Static IP lease to the client/host to which you are setting
up forwarding. This way, the IP does not change and disrupt your forwarding rules.
For example, if you are hosting a Web server in your internal network and you wish to
setup a forwarding rule for it, you should assign a static IP lease to that system to
keep the IP from renewing and disrupting the forwarding rule.
