Understanding Web Publishing
In Forefront TMG, to publish a Web site means to make a site on your internal network available from the Internet. When you publish a Web site for external access, you make the content you choose available to the users you choose.

Web publishing rules apply to Web requests for specific URLs that are received by a chosen network interface—typically the external interface of the Forefront TMG computer.

Requests that are allowed are then routed to an internal server specified in the publishing rule.
