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 the 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 internal site name must be installed on the published server. For more information about obtaining and installing SSL server certificates, see Configuring server certificates for secure Web publishing.
  • Forefront TMG treats a farm of servers behind a load-balancing device as a single server. Although this option is supported for publishing a load-balanced farm, we recommend that you use the integrated load-balancing support that is provided by a server farm created in Forefront TMG rather than a load-balancing device. Forefront TMG publishing for server farms provides improved client affinity, which can be configured to operate using a cookie, rather than depending on the client IP address. This is a distinct advantage in a situation where a device between the load-balancing device and Forefront TMG, such as a NAT device, hides the client IP address.
  • 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.
