Notes

• For more information about Web listeners, see Web listener overview.
• When publishing over SSL, an SSL server certificate that was issued to the public host name of each published Web site must be installed in the Personal store for the local computer on the Forefront TMG computer. If the Web publishing rule requires an SSL connection between the Forefront TMG computer and the published server, an SSL server certificate that was issued to the host name specified as the applicable internal site name must be installed on each published server. For more information about obtaining and installing SSL server certificates, see Configuring server certificates for secure Web publishing.
• This procedure creates a separate Web publishing rule for each published site specified.
• When you publish multiple Web sites according to this procedure, the public name suffix is appended to each of the internal site names that you specify. For example, if you want to publish the sites news.fabrikam.com, sports.fabrikam.com, and weather.fabrikam.com, specify the internal site names news, sports, and weather, and then provide the public name suffix fabrikam.com. The wizard will create three Web publishing rules, one for each of the sites, each using the same Web listener.
• You can configure the way in which credentials are passed to the published server in a Web publishing rule. For more information, see About delegation of credentials. 
• 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 Overview of Web publishing concepts.
