    Do not select Forefront TMG will use SSL to connect to the Web site.

    Published Web Sites Public Names

    Public name suffix

    Type the suffix that will be appended to the internal site names that are specified on the Specify Web Sites to Publish page to create the public names that users will use to access the published Web sites.

    Select No delegation, and client cannot authenticate directly.

    User Sets

    This rule applies to requests from the following user sets

    Do not change the default option, All Users.

Notes

  • The Web listener can also be configured for HTTP authentication or forms-based authentication. However, client authentication will then be performed over HTTP without encryption. Because user credentials will be transmitted in plain text, such configurations are considered insecure and are disabled by default. To enable such a configuration, open the properties of the Web listener. On the Authentication tab, click Advanced, and then select the Allow client authentication over HTTP check box. For best security practices, use such a configuration only if you have an SSL accelerator in front of the Forefront TMG computer. For more information about Web listeners, see Web listener overview.
  • This procedure creates a separate Web publishing rule for each published site specified, but they all use the same Web listener.
  • 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.
