Note:

The internal site name must be resolvable to an IP address. Forefront TMG automatically creates a link translation mapping between the internal site name and the first public name that is specified in the rule. This mapping is used to translate links that use the internal site name to reference the server farm on Web pages and in e-mail messages that external users may receive. By default, Forefront TMG changes the original Host header that is supplied by a browser application to a Host header that corresponds to the internal site name. You can configure the way in which credentials are passed to the published server in a Web publishing rule. Web publishing rules match incoming client requests to the appropriate Web site on the Web server. You can create Web publishing rules that deny traffic, to block incoming traffic that matches the rule conditions. Forefront TMG does not treat paths as case-sensitive. If your Web server includes both foldera and folderA, and you publish a path to one of the folders, both folders will be published. For more information about other settings in Web publishing rules, see Planning for publishing.
